Privacy Policy
Last updated: September 7, 2026
This Privacy Policy explains how Annotium ("the App"), developed by Hoang Le ("we", "us", "our"), handles information when you use it. Annotium does not require an account, does not run its own server, and does not upload your photos anywhere on its own — most of what the App does happens entirely on your device. This policy also covers the third-party services the App relies on for advertising, crash reporting, and purchases.
1. Information We Do Not Collect
We do not require you to create an account, and we do not operate servers that store your photos, annotations, notes, or project files. Your photos and edits stay on your device (and in your device's photo library / iCloud or Google Photos backup, governed by Apple's or Google's own policies) unless you explicitly export or share them yourself.
2. Permissions the App Requests
| Permission | Why |
|---|---|
| Photo library (read & save) | To let you pick a photo to annotate and save the annotated result back to your gallery. Only photos you actively pick or save are touched. |
| Camera | To let you take a new photo to annotate directly, instead of picking an existing one. |
| Location (while using the app) | Only used if you choose to insert a location stamp into a note — your coordinates are embedded into that note/project locally and are never sent to us. If you don't use this feature, your location is never read. |
You can decline or later revoke any of these permissions in your device's system settings; the App will simply be unable to offer the corresponding feature.
3. Advertising (Google AdMob)
The free tier of the App shows ads served by Google AdMob. AdMob and its partners may collect device identifiers (such as your device's advertising ID) and other technical data to serve and measure ads, including personalized ads where you have consented to tracking (on iOS, via Apple's App Tracking Transparency prompt). Purchasing Annotium PRO removes ads and stops this data collection going forward. See Google's own policies for how AdMob handles data:
4. Crash Reporting and Analytics
We use Firebase Crashlytics and Firebase Analytics to understand crashes and general, aggregated app usage (for example, which features are used and on which device types), so we can fix bugs and improve the App. This data is technical/diagnostic (device model, OS version, crash logs, anonymized usage events) and is not linked to your photos or annotation content. See Firebase's privacy documentation.
5. Purchases
In-app purchases (the PRO subscription and the legacy one-time purchases) are processed entirely by Apple's App Store or Google Play. We receive confirmation that a purchase was made (so the App can unlock the corresponding features) but we do not receive or store your payment card details — those are handled solely by Apple/Google under their own privacy policies.
6. Fonts and Network Access
If you use the App's optional Google Fonts catalog to browse or download additional fonts, your device fetches those font files directly from Google's font-serving infrastructure, subject to Google's own privacy policy. If you import your own local font files instead, nothing is sent anywhere.
7. Data Storage and Retention
Your projects, photos, notes, and app preferences are stored locally on your device (and your device's own encrypted secure storage for purchase-entitlement flags). Uninstalling the App removes this local data. We do not retain a copy of it, since we never received it in the first place.
8. Children's Privacy
The App is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has provided personal information through a third-party service integrated into the App, contact us and we will take appropriate steps.
9. Your Choices
- Revoke camera, photo library, or location permissions any time in your device settings.
- Decline or reset ad tracking consent (App Tracking Transparency on iOS, or your device's ad settings on Android) to limit personalized advertising.
- Purchase Annotium PRO to remove ads entirely.
- Uninstall the App to remove all locally stored data.
10. Changes to This Policy
We may update this Privacy Policy from time to time. Material changes will be reflected by an updated "Last updated" date above. Continued use of the App after changes take effect constitutes acceptance of the revised policy.
