1Who we are
AllerRadar (“the app”, “we”, “us”, “our”) is an iOS application published by Andrii Matiushev, publishing as “Zydeno” (“the developer”), the data controller responsible for this app. You can reach us any time at [email protected] or via zydeno.com.
Developer / data controller: Andrii Matiushev, independent developer publishing as “Zydeno” (Ukraine). For privacy questions, the fastest route is email.
2Scope of this policy
This policy explains how the AllerRadar iPhone app, its Apple Watch app, and its Home Screen widgets handle information. It does not cover third-party services the app contacts to fetch public data (see §6) — each of those has its own privacy policy — nor Apple’s App Store, which is governed by Apple’s Privacy Policy.
3What we do not collect
Because AllerRadar has no backend, the developer collects no personal data about you. Specifically, we do not:
- require or offer an account, login, email, or phone number;
- run any AllerRadar server that receives, logs, or stores your data;
- embed advertising, analytics, attribution, or crash-reporting SDKs;
- assign you an advertising identifier, device fingerprint, or tracking ID;
- track you across other apps or websites (so iOS App Tracking Transparency is not used);
- receive your name, address, or payment details when you buy AllerRadar Plus — all payments are processed by Apple (see §7);
- sell, rent, or share your personal information with data brokers — there is nothing for us to sell.
This corresponds to a “Data Not Collected” App Privacy label on the App Store. The app also ships with an Apple Privacy Manifest declaring no tracking and no collected data types.
AllerRadar is actively developed. The app offers an optional paid upgrade, AllerRadar Plus — processed entirely by Apple without giving us any personal data (§7). Beyond that, we don’t promise the app will stay ad-free forever: future versions may introduce advertising or analytics, which can involve collecting or sharing some data. If we make such a change, we will revise this policy and the App Store privacy label, and (where the law requires it) ask for your consent, before the change takes effect. Everything above describes the app as it works today.
4Data stored on your device
Everything you create lives only on your device (using Apple’s on-device SwiftData store and standard app preferences). It is included in your encrypted device backups if you back up your iPhone, but it is never sent to us and there is no iCloud sync. This includes:
- Allergen & diet profiles — including any number of family/member profiles, the allergens and diets you avoid, per-allergen severity, custom ingredients to avoid, and the pollens you react to;
- Symptom diary — your logged symptoms and their severity, treatments, free-text notes, overall daily feeling, and the pollen/air snapshot and products attached to each day;
- Scan history & favorites — products you scanned or looked up, including label-photo (OCR) scans;
- Shopping list items;
- Saved locations and forecast preferences;
- App settings — units, alert thresholds, AQI standard, reminder times, Face ID lock toggle, language.
You stay in control: you can edit or delete any item in the app, and deleting the app removes all of it (see §15).
5Health-related data
Allergen profiles and symptom-diary entries may reveal information about your health. We treat this as sensitive. Because it never leaves your device and we have no way to access it, this data is not collected or processed by us. You may additionally protect your diary and insights behind Face ID / Touch ID in Settings.
AllerRadar does not use Apple HealthKit and does not read from or write to the Apple Health app.
6Data sent to third-party data providers
To look things up, the app contacts free, public data services over a secure (HTTPS) connection. We do not operate these services and do not control how they handle requests; their own privacy policies apply. We send only the minimum needed for each lookup and attach no name, account, device ID, or other identifier.
| When this happens | What is sent | To whom | Why |
|---|---|---|---|
| You scan a food/cosmetic barcode or open a past scan | The product barcode number | Open Food Facts / Open Beauty Facts | To return ingredient, allergen, additive and nutrition data |
| You search for or browse alternative products (Discover) | The search text / category you choose | Open Food Facts / Open Beauty Facts | To find matching or healthier products |
| You view the pollen & air-quality forecast (or a widget/Watch refresh runs) | Approximate latitude/longitude | Open-Meteo (weather & air-quality APIs; pollen sourced from Copernicus/CAMS) | To return the local pollen, air-quality and weather forecast |
| You search for a city by name | The place name you type | Open-Meteo geocoding | To find matching locations and their coordinates |
| You open Recall alerts (US food recalls) | A generic recall query, or an optional brand name you enter | openFDA (U.S. Food & Drug Administration) | To list recent US food recalls |
Your IP address is inherently visible to any server you connect to (this is how the internet works) and may be processed transiently by these providers or their hosting/CDN to deliver a response. We do not receive or store it.

7Purchases & subscriptions (AllerRadar Plus)
AllerRadar offers an optional paid upgrade, AllerRadar Plus — an auto-renewing subscription (monthly or yearly, optionally starting with a free trial) or a one-time “Lifetime” purchase. Plus changes nothing about the app’s zero-collection design:
- Apple processes the payment. Purchases are made through your Apple Account under Apple’s Media Services Terms & Conditions. We never receive your name, email, billing address, or payment-card details. Apple’s handling of this data is described in Apple’s Privacy Policy.
- The app only verifies your entitlement. Using Apple’s on-device StoreKit framework, the app receives a signed, pseudonymous transaction record (the product purchased, a transaction identifier, purchase/expiry dates, and trial/refund status) that contains no contact or payment information. It is used solely to unlock Plus features and show your plan in Settings, and it is processed and stored on your device — we run no server it could be sent to.
- “Restore Purchases” simply asks the App Store (Apple) to re-check your entitlement for your Apple Account on the current device.
- Sales reports are aggregate. Apple provides developers with sales statistics that do not identify individual customers.
You can manage or cancel the subscription in your App Store account settings; refunds are requested from Apple. Billing, renewal and cancellation terms are in the Terms of Use (§12).
8Device permissions we may request
iOS will ask your permission before the app can use any of the following. Each is optional, used only for the stated purpose, and can be changed at any time in iOS Settings → AllerRadar.
| Permission | Why AllerRadar asks | What leaves the device |
|---|---|---|
| Camera | To read product barcodes and to photograph an ingredient label for on-device text recognition | Nothing — images are processed on-device and never stored or uploaded |
| Photo Library | If you pick an existing photo of an ingredient label to scan | Nothing — the chosen image is read on-device only |
| Location (While Using) | To show the pollen & air-quality forecast where you are | Only your approximate coordinates, only to the forecast provider (§6). You can skip this and search a city instead |
| Face ID / Touch ID | To optionally lock your symptom diary & insights | Nothing — biometric matching is handled entirely by iOS; we never see your biometrics |
| Notifications | For local pollen-spike alerts and an optional daily diary reminder | Nothing — notifications are scheduled on-device (see §11) |
| Background App Refresh | To occasionally refresh the forecast so alerts/widgets stay current | Only your saved coordinates to the forecast provider (§6) |
9On-device processing
All of AllerRadar’s “intelligence” runs locally on your device. Nothing below is uploaded anywhere:
- Ingredient-label text recognition (OCR) uses Apple’s on-device Vision framework;
- Allergen/diet matching and the Safe / Caution / Avoid verdict, health score, Nutri-Score and NOVA display;
- Insights that correlate your diary with food and environmental exposure, and the personalized symptom forecast;
- PDF diary reports, generated on-device for you to share via the standard iOS share sheet at your discretion.
10Apple Watch & Home Screen widgets
The Home Screen widgets simply display a small snapshot (your local forecast and last scan) that the app saves into a private, on-device App Group container (group.com.zydeno.allerradar) shared only between AllerRadar and its own extensions on your device. The Apple Watch app is standalone: it fetches the forecast for its own location directly from the same public provider in §6 and stores nothing about you off-device.
11Notifications
AllerRadar uses only local notifications scheduled on your device — there is no push server and no remote-push token. Pollen-spike alerts are computed from the forecast you already loaded, and the optional daily reminder fires at a time you choose. The content of these notifications never leaves your device.
12International data transfers
Because the developer collects no personal data, there is no transfer of your data by us. When you trigger a lookup, the request in §6 may be served from infrastructure located outside your country (for example, the EU or US). Those providers operate independently under their own terms and safeguards.
13Legal bases for processing (GDPR / UK GDPR)
For users in the European Economic Area, the United Kingdom and similar jurisdictions: any limited, transient processing that occurs relies on these bases —
- Consent — for optional device permissions (camera, location, notifications), which you grant via the iOS prompt and can withdraw at any time in iOS Settings;
- Performance of our agreement with you / legitimate interests — to provide the core lookup features you request (e.g., sending a barcode to return ingredient data), in a data-minimizing, identifier-free way;
- Performance of a contract — to verify your App Store purchase on-device and unlock AllerRadar Plus when you buy it, using only the pseudonymous transaction record described in §7.
Data you store on your device is under your sole control and is not processed by us.
Wherever you live, the position is the same: because the developer collects no personal data in any country, the app meets the data-minimization requirements of comparable privacy laws worldwide in the same way.
14Your privacy rights
Depending on where you live, you may have rights to access, correct, delete, port, or restrict the processing of your personal data, and to object or withdraw consent (GDPR/UK GDPR), or to know, delete, correct and opt out of “sale”/“sharing” (CCPA/CPRA and similar US state laws). The same applies under comparable privacy laws worldwide — for example Brazil’s LGPD, Canada’s PIPEDA and Québec’s Law 25, the Australian Privacy Act, Japan’s APPI, South Korea’s PIPA, India’s DPDP Act, Switzerland’s FADP and others.
Because all your AllerRadar data is held only on your device and we hold nothing about you, you can exercise these rights yourself directly in the app: view and edit your profiles and diary, delete any entry, or remove everything by deleting the app. We have no copy to access, export, or erase on our side. If you have questions or believe we can help, contact [email protected]. You also have the right to lodge a complaint with your local data-protection authority.
“Sale” / “sharing” of personal information: The current version does not sell or share your personal information, and we have not done so in the preceding 12 months. We don’t promise this will never change — see §3 regarding possible future ad-supported versions, which would be disclosed here first.
15Data retention & deletion
We retain nothing, because we receive nothing. Data you create is kept on your device until you delete it. To erase everything: delete individual items in the app, or remove AllerRadar from your iPhone (and Apple Watch) — this permanently deletes its local store. Note that copies inside your own encrypted iPhone backups are governed by Apple’s backup settings, not by us.
If you purchased AllerRadar Plus, the record of that purchase belongs to your Apple Account and is created and retained by Apple under Apple’s own privacy policy (that is also what lets you restore purchases after reinstalling). The app itself keeps only a local “Plus is active” flag on your device, which is deleted with the app.
16Security
Your data benefits from iOS’s built-in app sandboxing and device encryption, and can be further protected with your device passcode and the app’s optional Face ID / Touch ID lock. All network lookups use encrypted HTTPS connections. No method of storage or transmission is 100% secure, but minimizing what is sent — and never attaching an identity to it — is our primary safeguard.
17Children's privacy
AllerRadar is rated 9+ on the App Store and is intended for a general audience. It does not knowingly collect personal information from anyone, including children under 13 (or the minimum age in your country, e.g., 16 in parts of the EEA). Since the app collects no personal data at all, it does not knowingly collect data from children. A parent or guardian may set up and manage profiles. If you believe a child has provided personal information in a way that concerns you, contact us — though, as noted, we hold no such data.
18Do-Not-Track & no sale of data
The current version of AllerRadar does not track users and therefore has nothing to disable in response to a browser/OS “Do Not Track” or Global Privacy Control signal, and it does not sell or share personal information or use it for cross-context behavioral advertising. If a future version introduces advertising or analytics, we will honor applicable opt-out signals and update this policy first (see §3).
19Medical disclaimer
AllerRadar provides general allergy, ingredient, pollen and air-quality information for educational purposes only. It is not a medical device and does not diagnose, treat, cure, or prevent any condition. Ingredient and forecast data come from third-party, often crowd-sourced sources and may be incomplete, outdated or inaccurate — always read the product’s physical label and confirm any allergy or health decision with a qualified professional.
Do not rely on the app to avoid an allergic reaction. In an emergency or a severe allergic reaction (anaphylaxis), call your local emergency number immediately.
See the Terms of Use for the full disclaimer and limitations.
20Changes to this policy
We may update this Privacy Policy to reflect changes to the app or the law. When we do, we will revise the “Last updated” date at the top and, for material changes, highlight them in the app or on this page. Your continued use of AllerRadar after an update means you accept the revised policy.
