MissOrBliss

Terms of Use

This is the agreement (the end-user licence, or “EULA”) between you and the developer of MissOrBliss. It explains what the app is — an informational wellness tool, not a medical device — how Premium subscriptions work, and the limits of our responsibility. Please read it: by using the app you accept it in full.

Effective: 26 July 2026 Last updated: 26 July 2026 Version 2.0

The short version (not a substitute for the full text)

🩺
Informational only — not a medical device

MissOrBliss does not diagnose pregnancy or anything else, is not cleared, approved or registered by any medical regulator, and never replaces a home test read by its own leaflet or a doctor. See §4.

📷
A photo reading describes a picture, not your body

The reader measures relative line strength in a photo. Lighting, timing, the test brand, evaporation lines and dozens of other factors can change what it sees. Always confirm the physical test yourself. See §5.

📅
Cycle predictions are estimates — never contraception

Fertile-window, ovulation and period estimates are arithmetic on the dates you enter. Do not use them to prevent or achieve pregnancy, or for any medical decision. See §6.

💳
Premium is billed by Apple, and renews automatically

Subscriptions renew unless you turn off auto-renewal at least 24 hours before the period ends. Prices, periods and any trial are shown in the app before you buy. Only Apple can refund. See §15.

⚠️
Provided “as is”, used at your own risk

The app is supplied in the form in which it exists, with all faults. We are not responsible for bugs, wrong readings, missed reminders, lost data or any financial loss. See §17, §18 and §19.

🔒
Your data stays on your device

No account, no servers, no analytics. What that means in detail is in the Privacy Policy, which forms part of this agreement.

01Agreement to these Terms

These Terms of Use (the “Terms”) form a binding agreement between you (“you”, “the user”) and Andrii Matiushev, an independent developer publishing as “Zydeno” (“we”, “us”, “our”, “the developer”), governing the MissOrBliss iOS application, any update, in-app purchase or subscription within it, and the pages at zydeno.com/missorbliss/* (together, the “Service”).

You accept these Terms by downloading, installing, opening or using the app, by accepting the in-app disclaimer gate, or by purchasing Premium. If you do not agree with any part of these Terms, do not use the app and delete it. That is your sole remedy for disagreeing with them.

These Terms incorporate the Privacy Policy, the disclaimers shown inside the app (including the disclaimer gate you accept at first launch and the footers displayed on result screens), and, where applicable, Apple's Media Services Terms and the Apple Licensed Application End User Licence Agreement. If a mandatory provision of Apple's standard EULA conflicts with these Terms, that provision prevails to the extent of the conflict; otherwise these Terms replace Apple's default EULA.

02Who may use the app

The App Store age rating for MissOrBliss reflects Apple's content-rating system; it is not a licence for a minor to use the app contrary to this section. The app is not directed to children — see Privacy Policy §21.

03What MissOrBliss is — and is not

3.1 What it is

MissOrBliss is a consumer wellness and informational app that helps you:

3.2 Regulatory status — what it is not

⚠️ MissOrBliss is not a medical device

The app is not a medical device, not an in-vitro diagnostic device, and not an accessory to one. It has not been cleared, approved, certified, CE-marked, registered or otherwise reviewed by the U.S. Food and Drug Administration, the European Medicines Agency, any EU notified body under the MDR or IVDR, the UK MHRA, Health Canada, the TGA, PMDA, NMPA, ANVISA, or any other regulatory authority anywhere in the world. It is not a clinical decision-support tool, not a laboratory test, not a companion to any regulated device or medicine, and not intended for the diagnosis, cure, mitigation, prevention, treatment or monitoring of any disease or condition.

You must not use the app as a medical device, present its output as a diagnostic result, or rely on it in any clinical, professional, occupational, legal, insurance or forensic context. Doing so is a misuse of the app, is outside the licence granted in §12, and is entirely at your own risk.

3.3 The app does not read your test — the test's own leaflet does

A home pregnancy test is a regulated product with its own instructions, its own reading window and its own manufacturer. The authoritative reading of your test is the one you make with your own eyes, following that leaflet, within the time it specifies — and, where it matters, the reading confirmed by a healthcare professional. MissOrBliss adds an informational description of a photograph; it never replaces, overrides or validates the physical test.

04No medical advice, no diagnosis, emergencies

🚑 If this is an emergency, stop reading and get help

If you have severe abdominal or shoulder pain, heavy bleeding, fainting, dizziness, fever, severe vomiting, signs of ectopic pregnancy or miscarriage, or any other symptom that worries you — contact your doctor or your local emergency number immediately. Do not use MissOrBliss to assess an emergency, and do not delay care because of anything the app shows. The app cannot detect, escalate or respond to a medical emergency.

You alone decide what to do with the information the app shows you, and you are solely responsible for those decisions and their consequences. See §18 and §19.

05The photo reader & its limits

5.1 What the reader actually does

The reader works entirely on your device. It looks for the test strip in your photo, corrects perspective, normalises lighting, locates the membrane area, builds a brightness profile along the strip and identifies peaks that may correspond to the control and test lines. It then reports, in words, what it measured — for example that a control line was found and how strong any second line is relative to it — together with a read-reliability and photo-quality assessment. Enhancement sliders change only how the image looks; they do not change the measurement.

5.2 What it cannot do

It cannot measure hormone levels, cannot know your test's brand, sensitivity or reading window, cannot know when you took the test, and cannot see anything that is not visible in the photo you supplied. Its output is an observation of an image — nothing more.

Factors that can make a reading wrong or misleading
  • lighting, shadows, glare, colour cast, screen filters, camera quality, focus, angle and distance;
  • photographing the test outside the reading window in its leaflet — too early, or after it has dried, when evaporation lines and colour changes commonly appear;
  • indent lines, dye run, flooding, damaged, expired or improperly stored tests;
  • diluted urine, testing at the wrong time of day, very early testing, or the “hook effect” at very high hormone levels;
  • unusual test formats, digital tests, non-standard strip geometry, printed or on-screen images of tests;
  • medical factors that affect any home test — recent pregnancy or loss, fertility medication containing hCG, certain medical conditions;
  • ordinary software limitations: detection errors, mis-located lines, and bugs.

5.3 How you must treat a reading

We make no representation or warranty of any kind about the accuracy, sensitivity, specificity, repeatability or reliability of any reading, and we publish no accuracy figure — because no such figure would be meaningful across the range of tests, cameras and conditions the app is used in.

06Cycle estimates — not contraception

Predicted period dates, cycle day, phase, ovulation estimates, fertile windows, regularity figures, two-week-wait information, basal-body-temperature analysis and the earliest sensible test date are arithmetic estimates calculated from the dates and values you enter, using conventional averages. They are not observations of your body, and they are not medical findings.

⚠️ Not a contraceptive and not a fertility treatment

MissOrBliss must never be used as a method of contraception, family planning or pregnancy avoidance, nor as a fertility treatment or a substitute for medical fertility care. It is not a fertility-awareness-based method, has not been validated as one, and provides none of the training, rules or safeguards such a method requires. If you rely on it to avoid or achieve pregnancy, you do so entirely at your own risk and against our express instruction. For contraception or fertility care, speak to a healthcare professional.

Estimates become less reliable — and may be plainly wrong — with irregular cycles, few logged cycles, hormonal contraception, breastfeeding, PCOS, thyroid or other endocrine conditions, perimenopause, illness, stress, travel, shift work, significant weight change and many other factors. A late or missed period, an unexpected estimate, or a temperature pattern in the app means nothing on its own. If something concerns you, talk to a healthcare professional rather than to the app.

07The symptom questionnaire

The questionnaire is an educational, self-reported checklist. It applies fixed weights to your answers and adjusts for the cycle day and lifestyle factors you select, then describes, in words, how many common early signs your answers describe and which of them contributed most.

Treat its output as a prompt to take a proper test and, if needed, to see a healthcare professional — nothing more.

08Reminders & notifications

Reminders are optional local notifications scheduled by iOS on your device. They are a convenience, not a service level.

Never rely on a reminder

Delivery depends on iOS, your notification and Focus settings, Low Power Mode, device state, time-zone and daylight-saving changes, background scheduling limits and factors we do not control. A reminder may be delayed, silenced, duplicated, mistimed or never delivered. To the fullest extent permitted by law, we accept no responsibility for any consequence of a reminder that did not arrive, arrived late, or arrived with the wrong content — including a missed test, a missed measurement, a missed appointment or any decision made because of it.

09Your content, photos & notes

Everything you create in the app — photos, notes, journal entries, logs and questionnaire answers — is yours. It stays on your device (Privacy Policy §4), and we claim no ownership of it, acquire no licence to it, and never receive it. We cannot moderate, review, restore or access it.

You are solely responsible for the content you create, and you confirm that:

10Data loss, backups & your responsibility

Because there is no account and no cloud copy, the only copy of your data is the one on your device, plus whatever backups you make yourself.

Back up your device — we cannot recover anything

Data can be lost through deletion (deliberate or accidental), a lost, stolen, damaged or reset device, an iOS or app update, a failed restore, a storage failure, a software defect, or your own use of “Delete all data”. Keeping backups is entirely your responsibility. To the fullest extent permitted by law, we are not liable for the loss, corruption, unavailability or irrecoverability of any data, photo, log, export or history, however caused — and we have no ability to restore it, because we never had a copy.

11Educational content & external links

The app contains short educational text, a glossary and links to independent health organisations (for example NHS, ACOG, Mayo Clinic, NIH NICHD, CDC and WHO). Those organisations are not affiliated with us and do not endorse, review or sponsor the app; their names and marks belong to them and are used only to identify a source.

12Licence

Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to download and use one copy of the app for your own personal, non-commercial use on Apple-branded devices that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms. The app is licensed, not sold, and we and our licensors retain all rights not expressly granted.

You must not, and must not permit anyone else to:

This licence ends automatically if you breach these Terms, and on deletion of the app.

13Acceptable use

You agree that you will not use the app:

We may, to the extent technically possible and lawful, suspend or terminate your licence for a serious or repeated breach — see §16.

14Intellectual property

The app and everything in it — code, algorithms, interface, design, layout, illustrations, icons, generated sounds, text, glossary, questionnaire and its scoring, the MissOrBliss and Zydeno names and marks, and the pages at zydeno.com/missorbliss/* — are protected by copyright, trademark, database and other laws, and are owned by the developer or its licensors.

Nothing in these Terms transfers any intellectual-property right to you. Third-party trademarks (including Apple, App Store, iPhone, iPad, iOS, Apple Health and HealthKit, and the names of the health organisations linked in the app) belong to their respective owners and are used only descriptively; their use implies no affiliation or endorsement.

If you believe something in the app infringes your rights, write to [email protected] with a clear description of the material, your rights in it, and your contact details, and we will review it promptly.

15Premium, billing, renewals & refunds

15.1 What Premium is

MissOrBliss can be downloaded and its core features used without a purchase — capturing and analysing a test photo, the manual line reader, image enhancement, the descriptive reading and notes, the symptom questionnaire, the cycle calendar and all logging, the journal, the Learn tab, and a limited number of your most recent readings. An optional upgrade, MissOrBliss Premium (“Premium”), unlocks additional features — for example the line-strength trend chart, side-by-side comparison of two readings, the advanced basal-body-temperature chart, PDF export, unlimited display of your test history, and the relaxation sounds.

The exact set of features included in Premium is what is shown in the app at the time, and it may change as the app develops. We may add, change, move or remove features, and may change which features require Premium and which do not. We do not promise that any particular feature will remain free, remain in Premium, or remain available at all — see §16.

15.2 Plans

PlanTypeRenewal
Premium MonthlyAuto-renewable subscriptionRenews every month until cancelled
Premium AnnualAuto-renewable subscriptionRenews every year until cancelled
Premium LifetimeOne-time purchase (non-consumable)Does not renew — see §15.7

Prices are not stated in this document because they are set per country and can change. The price, the billing period, the price per period, the length of any free trial or introductory offer, and the currency are always displayed in the app and on the App Store, in your local currency including any applicable taxes, before you confirm the purchase. Nothing is charged unless you confirm.

15.3 Billing & automatic renewal

15.4 Free trials & introductory offers

A plan may include an introductory free trial (for example, one week). Where one applies, its length and terms are shown on the purchase screen. You are not charged during the trial; the trial converts automatically into a paid subscription at the price shown unless you turn off auto-renewal at least 24 hours before it ends. Any unused portion of a free trial is forfeited when you purchase a subscription or the Lifetime unlock. Eligibility for introductory offers — normally one per Apple Account or family group — is determined by Apple, not by us, which is why a trial badge may not appear for every user.

15.5 Price changes

Prices may differ by country and may change over time. We may set different prices for new purchases at any time. If the price of an existing subscription increases, Apple notifies you in advance and, where required, asks for your consent before the new price applies; if you do not agree, you can cancel before the next renewal and keep access until the paid period ends.

15.6 Refunds & restoring purchases

15.7 About the “Lifetime” purchase

Lifetime is a one-time, non-consumable purchase tied to your Apple Account. “Lifetime” means for the lifetime of the MissOrBliss app as offered by the developer — it is not a promise that the app, any particular feature, any future feature, any operating-system compatibility or any level of support will remain available indefinitely, and it does not cover any separate app we may publish. If the app is discontinued or a feature is changed or removed, §16, §17 and §19 apply.

15.8 No responsibility for charges or financial loss

💳 Billing is between you and Apple

Every charge, renewal, trial conversion, tax, currency conversion and refund is handled by Apple through your Apple Account. We never process payments, never see your payment details, and cannot start, stop, change, refund or reverse any charge. It is your responsibility to check the plan, price, billing period, trial length and renewal terms shown before confirming, to keep track of what you have subscribed to, and to cancel in time if you no longer want it.

To the maximum extent permitted by applicable law, the developer is not responsible or liable for any charge, renewal, unwanted subscription, forgotten cancellation, trial that converted, non-refunded amount, duplicate purchase, unauthorised purchase made on your device or with your Apple Account, chargeback, currency-conversion cost, bank or card fee, tax, or any other financial loss arising from a purchase or from the use of, or inability to use, any paid feature. Those matters are governed by your agreement with Apple and by your own device and account settings. Nothing in this section removes any refund, cancellation or withdrawal right that mandatory consumer law gives you.

15.9 Advertising

The app may in future be supported by advertising in addition to Premium. We make no commitment that the app will remain free of advertising. If advertising is introduced, it may involve third-party providers with their own data practices; the Privacy Policy §12 and the App Store privacy label will be updated before any such component becomes active, your health data will never be used for advertising, and any advertising placement in the app will not be shown while Premium is active.

16Updates, availability & termination

17Disclaimer of warranties

Provided “as is”, with all faults

To the maximum extent permitted by applicable law, the app, every reading, estimate, chart, export, reminder and piece of content it produces, and the Service as a whole, are provided “AS IS” and “AS AVAILABLE”, with all faults and defects, and without warranty of any kind, whether express, implied or statutory.

We specifically disclaim all implied warranties and conditions of merchantability, satisfactory quality, fitness for a particular purpose, accuracy, completeness, reliability, quiet enjoyment, non-infringement, and any warranty arising from course of dealing or trade usage. Without limiting that, we do not warrant that:

No advice or information, oral or written, obtained from us or through the app creates any warranty not expressly stated here. You assume the entire risk as to the quality, performance and results of the app.

Consumers keep their statutory rights

Some jurisdictions do not allow the exclusion of certain warranties or conditions, so parts of this section may not apply to you. Nothing here excludes, restricts or modifies any right, guarantee or remedy that mandatory consumer law gives you and that cannot lawfully be waived — for example the legal guarantee of conformity for digital content and services in the EU and UK, the consumer guarantees under the Australian Consumer Law, and equivalent protections elsewhere. Where such rights apply, they prevail over this section to the extent of any conflict, and any warranty is limited to the minimum scope permitted by law.

18Assumption of risk — use at your own risk

You expressly acknowledge and agree that your use of MissOrBliss is entirely at your own risk, and that the app is supplied in the form in which it exists, with all its limitations and faults, without any commitment that it will work as you expect.

To the maximum extent permitted by applicable law, you assume full responsibility for, and the developer is not at fault for and bears no liability for:

If you are not satisfied with the app, or do not agree with these Terms, your sole and exclusive remedy is to stop using it and delete it (and, for any purchase, to request a refund from Apple under §15.6). This section does not remove any right you have under mandatory consumer law that cannot be waived.

19Limitation of liability

To the maximum extent permitted by applicable law, in no event will the developer, or its officers, employees, contractors, licensors or suppliers, be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenue, savings, data, goodwill, opportunity or reputation, or for any personal injury, emotional distress, medical cost, pregnancy-related cost, or financial loss, arising out of or relating to:

— even if we have been advised of the possibility of such damages, and regardless of the legal theory (contract, tort, negligence, strict liability, statute or otherwise).

Cap. To the maximum extent permitted by law, our total aggregate liability for all claims relating to the app or these Terms will not exceed the greater of (a) the total amount you actually paid through Apple for MissOrBliss and its in-app purchases in the twelve (12) months before the event giving rise to the claim, or (b) USD 10.

What cannot be excluded stays

Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited — including, where the law so provides, liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, for gross negligence or wilful misconduct, and liability under mandatory product-liability or consumer-protection law. Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you, and you may have additional rights that vary by country. Where a limitation is unenforceable, it applies to the greatest extent permitted.

20Indemnification

To the extent permitted by law, you agree to indemnify, defend and hold harmless the developer and its officers, employees, contractors, licensors and suppliers from and against any claim, demand, damage, loss, liability, cost or expense (including reasonable legal fees) arising out of or connected with: your misuse of the app (including any use contrary to §3, §4, §6 or §13); your content; your breach of these Terms; your use of the app in a professional, clinical or commercial context; or your violation of any law or of any third party's rights.

21Apple-specific terms

These Terms are concluded between you and the developer only, not with Apple Inc. (“Apple”). Apple is not responsible for the app or its content. Because the app is downloaded from the Apple App Store, the following also apply:

22Export controls & sanctions

You agree to comply with all applicable export-control and sanctions laws, including those of the United States, the European Union and the United Kingdom. You may not use, export or re-export the app in violation of those laws, or use it if you are a person or entity subject to applicable sanctions or restrictions. The app contains no proprietary encryption beyond what is exempt under applicable regulations, and uses only the standard encryption provided by iOS.

23Governing law

These Terms, and any dispute or claim arising out of or in connection with them or their subject matter (including non-contractual disputes), are governed by the laws of the country in which the developer is established, without regard to its conflict-of-law rules and excluding the United Nations Convention on Contracts for the International Sale of Goods.

If you are a consumer, your own law still protects you

This choice of law does not deprive you of the protection of the mandatory consumer-protection provisions of the law of the country in which you habitually reside. If you are a consumer in the EEA, the UK, Switzerland, Australia, Canada, Brazil or any other jurisdiction with such rules, you keep those protections and may bring proceedings in the courts of your own country where the law gives you that right.

24Dispute resolution

24.1 Talk to us first

Most problems can be solved by email. Before starting any formal proceeding, please contact [email protected] with a clear description of the issue, the app version, your device, and the outcome you are seeking. We will try in good faith to resolve it within 60 days. This step is a condition of bringing a claim, except for a claim in a small-claims court or for urgent injunctive relief.

24.2 Courts and arbitration

Unless mandatory law provides otherwise, any dispute that is not resolved informally will be submitted to the exclusive jurisdiction of the competent courts of the country in which the developer is established. Where both parties agree in writing, a dispute may instead be finally settled by binding arbitration in that jurisdiction, conducted in English by a single arbitrator, with each party bearing its own costs unless the arbitrator decides otherwise.

24.3 If you are in the United States

To the extent permitted by the Federal Arbitration Act and applicable law, you and the developer agree that any dispute that is not resolved under §24.1 will be resolved by binding individual arbitration rather than in court, except that either party may bring an individual claim in a small-claims court, and either party may seek injunctive relief for intellectual-property misuse. You and the developer waive any right to a jury trial and to participate in a class, collective, consolidated or representative action, to the maximum extent permitted by law. If the class-action waiver is held unenforceable as to a particular claim, that claim proceeds in court and the rest of this section remains in force.

30-day opt-out. You may opt out of the arbitration agreement and class-action waiver in §24.3 by emailing [email protected] with the subject line “Arbitration opt-out” within 30 days of first accepting these Terms. Opting out does not affect any other part of these Terms, and will not be held against you in any way.

24.4 Consumer alternative dispute resolution

Consumers in the EEA and the UK may be entitled to use a national alternative-dispute-resolution or consumer-ombudsman body. We are not obliged to participate in proceedings before a consumer arbitration board and, as a rule, do not — but we will always try to resolve your issue directly by email first. Whatever this section says, you keep any right you have under mandatory law to bring proceedings in your own courts.

24.5 Time limit

To the extent permitted by law, any claim relating to the app must be brought within one (1) year of the event giving rise to it, or it is permanently barred. Where mandatory law provides a longer limitation period that cannot be shortened, that period applies instead.

25Consumer rights by region

MissOrBliss is available worldwide, and consumer law differs everywhere. These Terms are written to apply globally, but they never override a protection you cannot waive.

Where you areWhat still applies, whatever these Terms say
EEA & UK The legal guarantee of conformity for digital content and services; the 14-day right of withdrawal for digital purchases (exercised through Apple, and subject to the immediate-performance exception); unfair-terms protection; the right to bring proceedings in your country of residence; and the right to rely on mandatory consumer law where it conflicts with §23.
Australia The consumer guarantees under the Australian Consumer Law, which cannot be excluded. Where the law permits, our liability for failure to comply with a non-excludable guarantee is limited to re-supplying the app or paying the cost of re-supply.
New Zealand The Consumer Guarantees Act, where you acquire the app as a consumer.
Canada Provincial consumer-protection law, including Quebec's Consumer Protection Act; some limitations in these Terms may not apply to you.
Brazil & Latin America The Brazilian Consumer Defence Code (CDC) and equivalent national consumer statutes, including rules on defects, information and unfair clauses.
United States State consumer-protection statutes and any non-waivable rights; some states do not allow the exclusion of implied warranties or of incidental or consequential damages, so parts of §17 and §19 may not apply to you.
Elsewhere Any mandatory consumer or product-safety protection in your country of residence applies and prevails over any conflicting provision here, to the extent of the conflict.

26General provisions

27Changes to these Terms

We may update these Terms as the app changes or as the law develops. The current version is always published at zydeno.com/missorbliss/terms.html, with the “Last updated” date and version shown at the top.

Material changes take effect when the updated Terms are published, or on the date stated in them, and where the law requires it we will bring them to your attention in the app. Continuing to use the app after an update means you accept the updated Terms. If you do not accept them, stop using the app and delete it; for an active subscription, you may also cancel auto-renewal as described in §15.3.

28Contact

Please include the app version (Settings → About), your device model and iOS version, and a description of the issue. For anything about billing, renewals or refunds, contact Apple first (§15.6) — we have no access to your purchases.

One last reminder

MissOrBliss is an informational wellness app, not a medical device and not a diagnosis. Whatever the app shows you, confirm it with a home test read by its own leaflet, and talk to a doctor about anything that matters. Read the Privacy Policy as well — it forms part of this agreement.
