Dental Diary Privacy Policy

Effective date: October 25, 2026

This policy explains what data the Dental Diary Android app ("the app") handles, where it is stored, and who can access it. We have tried to keep it short and in plain language.

1. Who we are

The app is developed and published by Mr.ozon1982 ("the developer", "we", "us").

For any question about your data or this policy, contact us at mr.ozon1982@gmail.com.

2. Data you enter

You enter information about yourself and your family members:

• profiles: name, date of birth, dentition type (primary, mixed, permanent), note;
• treatment records: date, procedure type, teeth (FDI numbers), cost, warranty end date, next check-up date, comment;
• lists: doctors (full name, phone, note) and clinics (name, address, phone, note);
• app settings (for example, whether to use wallpaper colors).

This data — including information about dental health and spending — is stored only on your device. The app requires no sign-up, creates no account, does not sync to any cloud, and does not send your data to the developer or any third party. We have no servers that store your records, so we cannot view, recover, or delete them.

3. Backups

• Android automatic backup is disabled. App data is not included in Google cloud backups and is not copied when you set up a new phone using Android's transfer tools.
• Export to a JSON file happens only when you choose it (Settings → Backup → Export to file…). The file is saved through the system file picker to a location you choose — device storage, a memory card, or a cloud storage app installed on your device. From then on, the file is handled under the rules of the storage you chose.
• The backup file is not encrypted and contains all your records, including health information. Keep it safe and do not share it with others.
• Import reads only the file you select and replaces the current data in the app.

4. Advertising

The app is free and shows banner ads using the Yandex Mobile Ads SDK (Yandex LLC). Banners appear on some screens (for example, Profiles, Settings, FDI guide, and About).

To serve and measure ads, the SDK may process technical device data and information about your interaction with ads, such as device model, operating system version, device language and settings, IP address, network connection type, ad impressions and clicks, and diagnostic data about the SDK's operation. The exact data set is determined by Yandex.

We have configured the SDK to limit data collection:

• the app does not request the Google Advertising ID (the com.google.android.gms.permission.AD_ID permission is removed from the app);
• location tracking in the SDK is turned off, and the app has no location permissions;
• age-restricted mode is enabled (limited data processing);
• the app does not pass consent for ad personalization, so ads are non-personalized.

Yandex processes this data under its own privacy policy: https://yandex.com/legal/confidential/

5. What we never share with the ad SDK

The data you enter in the app (names, dates of birth, treatment records, teeth, amounts, doctors, clinics, comments) is not passed to the ad SDK and is not used to select ads. We do not sell or rent any data.

6. Permissions and network requests

The app uses only network-related permissions:

• internet access and network state — to load ads and to check for app updates through Google Play;
• the Google Play Install Referrer service — connected by the ad SDK's libraries for technical install attribution.

The app does not request access to your contacts, camera, microphone, photos, location, or notifications. File access is limited to the single file you pick when exporting or importing.

Update checks use Google Play's built-in in-app update mechanism (Play Core), at most once a day. Google handles this data under its own policy: https://policies.google.com/privacy. The version of the app installed from RuStore checks for updates through the RuStore SDK under RuStore's rules.

Feedback and ratings. If you email us from the app, your own email app opens; we receive your address and message and use them only to reply. The rate button opens the app's store page.

7. Children

The app is intended for adults and is not designed to be used by children on their own. Information about children (for example, a child's profile and treatment records) is entered by parents or legal guardians; like all other data, it stays on the device and is never sent to the developer.

8. Deleting your data

• Deleting a profile in the app removes that profile and all of its treatment records.
• Uninstalling the app or clearing its data in Android settings erases all app data from the device. Because automatic backup is disabled, it can only be restored from a JSON file you exported earlier.
• Delete exported backup files yourself wherever you saved them.

Since the developer does not store your data, you do not need to send us a deletion request. For data processed by Yandex, contact Yandex as described in its policy.

9. Changes and contact

We may update this policy, for example when new features are added. The new version will be published at this same address with an updated effective date; we will mention significant changes in the Google Play release notes.
