Privacy Policy

1Who we are

Lovagehum is an Android app by Zydeno for working with PDF documents and paper on your phone: combining PDF files and photos, arranging, rotating, removing and splitting pages, making files smaller, filling in forms, adding a drawn signature or initials, hiding selected text, removing document information such as the author or the place a photo was taken, and scanning paper with the camera. Contact [email protected] about this policy or your privacy. This policy covers the Android app only. It does not cover Google Play, Android itself, your camera hardware, your browser, your e-mail app, a document or cloud provider you choose in the Android file picker, or any other app; each of them has its own policy.

2Scope and current version

This policy describes Lovagehum version 1.0 for Android as reviewed on 22 October 2026. The current version works fully offline. It has no user accounts, no ads, no in-app purchases, no analytics, no advertising identifier and no third-party crash-reporting or tracking SDKs. The app does not connect to a Zydeno server or to any other server.

3What we do not collect

We, the developer, do not receive anything you open, scan, enter or produce in the app. Through the app we do not collect, store on a server, sell or share your documents, photos, camera images, page contents, file names, drawn signatures, passwords, document information, settings, usage events, device identifiers, advertising ID, contacts, location, microphone audio or device diagnostics. Nothing is used for advertising or profiling.

Documents and photos often contain personal data about you and other people, such as names, addresses, signatures, identity numbers, health or financial details. They stay on your device under your control, as described below; we simply never receive them.

4What stays on your device

Lovagehum keeps the following in the app’s private storage on your phone, which other apps cannot read:

• Copies of the files you open: when you pick a PDF or a photo, the app makes a private copy so that it can work safely and never changes your original. These copies keep everything the original contained, including document information and photo metadata such as the date, the camera model or the place where a photo was taken.
• Scanned pages: the original camera images of pages you scan or import, with the edges and settings you chose, so that you can adjust a page again without losing quality.
• Finished documents: PDF copies the app has produced and checked, until you save them elsewhere or delete them.
• Work in progress: temporary files and a short record of a running task (its step and progress), so that the app can show progress and recover after an interruption. They are deleted when the task ends or when you delete all data.
• Saved signatures and initials: only if you choose “Keep it on this phone” after drawing a signature or taking it from a photo of your signature on paper. You can delete them at any time in Settings → Your data. Signatures already placed in a PDF stay in that file.
• Form entries: text you type into a form is held by the app while you fill it in and is then written into the new copy you make, which is kept as a finished document.
• Recent saves: the names of copies you saved and the places you chose, so that the app can open them again, finish or clean up a copy interrupted while it was being saved, and show you where your file went.
• Settings: language, theme, paper size and unit preferences, haptic and sound preferences, and similar choices.

Passwords you type to open or protect a PDF are used only in the phone’s memory for that task and are cleared afterwards. The app does not save them, write them to its records or put them on the clipboard.

Long tasks run in a separate, private process of the app on your phone, so that a damaged or very large file cannot freeze the screen. That process belongs to Lovagehum, is not available to other apps and has no network access.

These records remain until you delete them, clear the app’s storage or uninstall the app. They are not transmitted to us.

5Camera and scanning

You never need to give camera access: you can import photos of paper through the Android file picker instead. The app asks for Android’s camera permission only when you open the scanner and tap to enable the camera.

• The camera runs only while the scanner is on screen. It stops when you leave the scanner or the app, and the app never uses the camera in the background.
• While the scanner is open, the app analyses the live picture on the phone to find the edges of the page and to take a picture automatically when the page is steady, if you leave automatic capture on. Live frames are processed in memory and are not stored; only the pages you capture are kept, as described in §4.
• The app does not record video or sound, does not use the microphone, does not recognise faces or people, and does not read your location.
• You can deny or withdraw camera access at any time in Android Settings → Apps → Lovagehum → Permissions. Everything else, including importing photos, keeps working.

When the app makes a new PDF from a photo or scan, it leaves out the photo’s embedded metadata, such as its location, device and author fields, while keeping the colour information. The private original image in the app, and a full backup you export, still contain the metadata of the original.

6Offline operation and external links

The app does not request Android’s INTERNET or network-state permission and contains no network code. Reading, changing, compressing, checking and scanning documents all happen on the device with software packaged in the app (see §9). Nothing is fetched from or reported to a server, and no document is uploaded for processing.

The app shows links to this policy and to the Terms of Use. They open in your browser only when you tap them; the browser then contacts that website under its own settings, and the website may log technical data such as your IP address. The support link opens your e-mail app with our address filled in; nothing is sent unless you send the e-mail yourself, and no document from the app is attached. Android and Google Play may, as part of the operating system, update the app or system components such as fonts under Google’s own terms; that is not done by Lovagehum.

7Opening, saving and backups

Lovagehum has no storage or photo-library permission. It reaches your files only in ways you start: through Android’s system file picker (the Storage Access Framework), which gives the app access only to the files or folder you pick, or when you send a PDF or photo to Lovagehum from another app with Share or Open with:

• Opening: the PDFs and photos you select, or send to Lovagehum from another app, are copied into the app’s private storage. The app does not browse or index your other files.
• Saving: a finished PDF is written only to the place and file name you choose. If you save pages as pictures, you pick a folder and the app writes the pictures there. Android keeps the app’s access to a file or folder you chose until the copy is finished, so that an interrupted save can be completed or cleaned up; the app does not read anything else there. Your original files are never overwritten.
• Share and Open: when you tap Share or Open, Android shows a list of apps and the app you choose receives that one file under its own terms. Nothing is sent until you choose an app.
• Backup (Settings → Your data → Export data): an archive of your documents, scanned pages, saved signatures and settings, saved where you choose. You can protect it with a password; the app then encrypts the archive on the phone (AES-256), does not keep the password and cannot open the archive without it. Without a password the archive is not encrypted. Either way it can contain the original photos with their metadata; the app says so before you export.
• Restore (Settings → Your data → Import data): the app checks the archive you pick before anything changes and lets you undo the restore.

If you choose a cloud-backed location in the file picker (for example a cloud drive), or later pass a saved file to another app, that provider or app receives the file under its own terms. That is a transfer you start and control, not a transfer to Zydeno. Protect the places where you store documents and backups.

8Permissions and backup

The app’s manifest declares only these permissions:

• Camera (CAMERA): optional, requested only when you enable the scanner, used only while the scanner is on screen (§5). The app also works on phones without a camera.
• An app-internal signature permission that Android libraries use to protect the app’s own components; it gives access to nothing about you. The advertising-ID permission is removed from the app.

The app requests no internet, location, microphone, contacts, photos and videos, storage or all-files, phone, SMS, calendar, notification, accessibility, foreground-service or exact-alarm permission.

• Haptics and sounds: vibrations use Android’s standard haptic feedback, which needs no permission. Any interface sounds are short sounds packaged with the app that play only after your own action. The app records nothing.
• Clipboard: the app does not monitor your clipboard.

Android automatic backup is turned off, and both cloud backup and device-to-device transfer are excluded for all app data. To move your documents, export a backup yourself and restore it on the other device.

9Bundled software

The app is built with AndroidX (including CameraX), Jetpack Compose, DataStore, Kotlin, kotlinx.coroutines and kotlinx.serialization under the Apache License 2.0. It reads and changes PDF documents with PdfBox-Android (Apache License 2.0, a port of Apache PDFBox), qpdf (Apache License 2.0) and Bouncy Castle (MIT-style licence), and encodes images with libjpeg-turbo (BSD-style and IJG licences) and zlib (zlib licence). It also uses the Android NDK C++ runtime and Unicode CLDR data under their own licences. The typefaces PT Sans Caption and STIX Two Text (for the interface) and Noto Sans (for text the app writes into a PDF), and Liberation Sans included with PdfBox-Android, are used under the SIL Open Font License 1.1.

These components run inside the app and send nothing anywhere. The app contains no advertising, analytics, social-media, payment, account, cloud or crash-reporting SDK, and no online text recognition or document-conversion service. Licence texts and notices are available offline in the app under Settings → Licences.

10Your choices and deletion

You can remove pages, scans and finished documents in the app, switch haptics and any sound options on or off, delete saved signatures, export a complete copy at any time and remove everything with Settings → Your data → Delete all data. Before deleting, the app asks you to confirm and offers to export a copy first. Deletion removes the app’s copies of your documents, scanned pages, finished documents, saved signatures, work in progress, temporary files and settings; the app then starts again from the first step. Clearing the app’s storage in Android Settings or uninstalling the app also removes its private data.

Deleting data in Lovagehum does not delete your original files, PDFs or backups you saved elsewhere, or copies held by a cloud provider or another app. Remove those yourself. Because we never receive your data, we cannot recover it for you or delete it remotely, and there is no account to close.

11Security and limitations

Android’s app sandbox keeps the app’s private storage separate from other apps. Lovagehum opens documents in a separate process with limits on size, memory and time, checks every copy before you save it and rejects malformed or oversized backup archives before restoring them. These measures reduce the risk from damaged or hostile files; they are not encryption, and the app is not a secure vault. Anyone who can get past your phone’s screen lock can open the app and see your documents. Loss, theft or failure of your device, or malware on it, can expose or destroy local records.

A password set on a PDF, hiding text or removing document information applies only to the new copy the app produces. It does not erase the original, earlier copies, backups, or data left in the phone’s storage hardware, and it does not make a document secret from someone who already has another copy. No security measure is perfect; keep your originals and a backup when your documents matter to you.

12Legal bases for processing

Where the EU or UK GDPR, or a similar law such as the Swiss FADP or Brazil’s LGPD, applies, these are the legal bases for the limited processing described in this policy:

The app makes no automated decisions that have legal or similarly significant effects on you, does not build a profile of you and does not analyse special categories of personal data. Documents and photos you open or scan may contain sensitive information, such as identity, health or financial details; they stay on your device under your control, and we process none of them.

13Retention and support

Data in the app stays until you delete it, clear the app’s storage or uninstall the app; files you saved or exported stay wherever you put them. Temporary task files are removed when the task finishes or is cancelled, and the copy kept to undo a restore is removed when you delete all data. If you choose to e-mail support, we receive your e-mail address, your message and anything you decide to attach. Please do not send documents, scans, signatures or passwords; if a file is needed to understand a problem, we will ask, and you can send a version without personal details.

14Ads, purchases and future versions

Today. The current version of Lovagehum is free of charge, shows no ads, has no in-app purchases or subscriptions, and contains no advertising, analytics or payment SDKs. This describes the app as it is now, not a promise about future versions. Future versions may introduce advertising, paid features, in-app purchases or subscriptions, or other optional services.

If ads are introduced. Ads would be supplied by a third-party ad network, for example Google AdMob. Ad networks typically process your device’s advertising ID, IP address, approximate location derived from the IP address, device and app information and your interactions with ads, in order to show ads, limit repetition, measure performance and prevent fraud, and, only where you allow it, to personalise ads. Ads would also require the app to connect to the internet, which the current version cannot do.

If purchases or subscriptions are introduced. They would be processed by Google Play’s billing system. Google handles your payment details under the Google Privacy Policy. We would receive only what is needed to deliver and verify a purchase, such as a purchase token, the product, its status, the country and the currency, never your full card or bank details.

Before any such change we will update this policy with a new effective date and version, describing what data is processed, by whom, why and how you can control it; update the Google Play Data safety section; mention the change in the release notes; ask for your consent where the law requires it (for example for personalised ads and non-essential access to your device in the EEA, the UK and Switzerland, through a consent tool that meets Google’s requirements); and offer the opt-outs the law requires (for example under US state privacy laws). The change applies only from the app version that introduces it. Data already stored in the app will not be used for advertising without telling you first and, where required, getting your consent. We will not knowingly show personalised ads to children (§15).

15Age and intended audience

Lovagehum is a general document tool intended for teenagers and adults aged 13 and above and is not directed to children under 13. The content rating shown on Google Play and the intended audience are separate things. The app has no chat, no public profiles and no way to contact other users.

16Your privacy rights

Privacy laws in many countries give you rights over your personal data. Because Lovagehum keeps your data on your phone and the developer does not receive it, most of these rights are in your own hands: you can view, correct, export and delete everything in the app (§10) and withdraw permissions in Android Settings. For data you have sent us, such as e-mails, write to [email protected].

EU and UK representative. The individual developer does not process personal data of people in the EU/EEA or the UK except occasional e-mails you choose to send to support. This occasional processing does not involve large-scale processing of special-category or criminal-offence data and is unlikely to result in a risk to your rights and freedoms. Under Article 27(2)(a) GDPR and Article 27(2)(a) UK GDPR, it does not require an EU or UK representative, so none is appointed. Contact us directly at [email protected]; you can also complain to your local supervisory authority.

Rights by region. A summary; the law where you live decides the details.

• European Union, EEA, United Kingdom and Switzerland (GDPR, UK GDPR, Swiss FADP): access, rectification, erasure, restriction of processing, data portability, objection to processing based on legitimate interests, withdrawal of consent at any time, and complaint to a supervisory authority, for example in the country where you live or work (in the UK, the Information Commissioner’s Office).
• United States (California CCPA as amended by the CPRA, and the comprehensive privacy laws of other states such as Virginia, Colorado, Connecticut, Texas and Oregon): to know and access, delete, correct and port personal information; to opt out of its sale or sharing, of targeted advertising and of profiling; to limit the use of sensitive personal information; to appeal a refusal; to use an authorised agent; and not to be discriminated against for using these rights. Notice for California residents: in the last 12 months the developer has not collected personal information through the app, other than e-mails you chose to send us. We have not sold or shared personal information, and we do not use sensitive personal information. Global Privacy Control signals are honoured where the law requires; today there is nothing to opt out of.
• Canada (PIPEDA and provincial laws, including Québec’s Law 25): access, correction and withdrawal of consent; complaints to the Office of the Privacy Commissioner of Canada or, in Québec, the Commission d’accès à l’information.
• Brazil (LGPD): confirmation of processing, access, correction, anonymisation, blocking or deletion, portability, information about sharing and revocation of consent; complaints to the ANPD.
• Japan (APPI): disclosure, correction, suspension of use or deletion; complaints to the Personal Information Protection Commission.
• South Korea (PIPA): access, correction, deletion, suspension of processing and withdrawal of consent; complaints to the Personal Information Protection Commission or the KISA privacy centre. The person responsible for personal information is the developer, reachable at [email protected].
• Australia and New Zealand (Privacy Act 1988, Privacy Act 2020): access and correction; complaints to the OAIC or the New Zealand Privacy Commissioner.
• Other countries (for example India’s DPDP Act, Singapore’s PDPA, South Africa’s POPIA or Türkiye’s KVKK): the rights your local law gives you. Write to us and we will respond in line with it.

How we respond. We answer within one month, or sooner or later where your local law sets another period (for example 45 days under the CCPA), and we may extend it where the law allows. We may ask for information to confirm that a request comes from you. Requests are free unless they are manifestly unfounded or excessive. If we cannot do what you ask, we explain why and how you can appeal or complain.

17International users

Lovagehum is available in many countries. The developer does not receive the data you keep in the app, so we do not transfer it anywhere.

If you e-mail us, your message is processed by our e-mail provider and may be stored on servers outside your country. Where the GDPR or UK GDPR applies to such a transfer, it relies on an adequacy decision, on standard contractual clauses offered by the provider, or on the transfer being necessary to answer your request.

This policy is written in English. If a translation is offered, the English version prevails unless your local law requires otherwise.

18Changes to this policy

We may update this policy when we change the app (including any change described in §14), when the services the app uses change, or when the law changes. The effective date and version at the top of this page show which version applies, and the version history (§19) summarises every change.

For a material change, for example new data leaving your device, ads or purchases, we update this page and the Google Play Data safety section before the app version with that change is published, describe it in the release notes, and ask for your consent in the app where the law requires it. Changes do not apply retroactively to data processed before them. Earlier versions are available on request from [email protected].
