Openings Atlas
Privacy Policy
Effective 1 November 2026 · Last updated 1 November 2026
The short version: Openings Atlas collects nothing. It has no accounts, no ads, no analytics and no internet permission, so there is no way for it to send information anywhere. Everything you save stays on your own device.
1. Who this policy covers
This policy applies to the Openings Atlas Android application
(package com.emptyfire.openingsatlas), published by Aaron Meyer
(“we”, “us”). It does not cover Google Play itself, or any other app or website you
may reach from it.
2. Information we collect
We do not collect any information about you. In particular, the app does not collect or transmit:
- names, email addresses, phone numbers, or any other contact details;
- account or login information — the app has no accounts;
- location data;
- device identifiers, advertising IDs, or IP addresses;
- usage, interaction, or diagnostic data;
- photos, files, contacts, microphone, or camera access.
We do not sell, rent, or share personal data, because we do not have any.
3. Information stored on your device
The app saves a small amount of data locally so it remembers your preferences between sessions. This data never leaves your device.
| Saved openings (“favourites”) | The identifiers of the openings you starred, in the order you saved them. |
|---|---|
| Skill level | The level you chose during setup (for example, “Club player”), used to pick which openings Browse shows. |
| Board appearance | Which board colour theme you last selected. |
This information is stored in the app's private storage area on your device. It is not readable by other apps, is not backed up to us, and is permanently deleted when you clear the app's data or uninstall the app.
4. Permissions
The app requests no Android permissions at all. That includes no internet permission, which means the app is technically incapable of sending or receiving data over a network. All 3,177 openings, the board, and the piece artwork are bundled inside the app.
5. Third parties
There are no third-party advertising, analytics, crash-reporting, or tracking services in this app. No third party receives information about you through it.
The opening names, ECO codes, and move sequences in the app come from the lichess-org/chess-openings dataset, which is public domain (CC0). That dataset contains no personal data and is bundled with the app rather than downloaded.
6. Children's privacy
The app is suitable for all ages and is not directed at children under 13 in any way that involves data collection. Because the app collects no personal information from anyone, it collects none from children.
7. Your choices
- Remove saved data: clear the app's storage in Android Settings → Apps → Openings Atlas → Storage → Clear data, or uninstall the app. Both erase favourites, skill level, and board theme.
- Change what you see: your skill level can be changed at any time from the Browse screen.
8. Changes to this policy
If the app later gains a feature that involves data (for example, optional cloud sync), this policy will be updated before that feature ships, and the “Last updated” date above will change. Material changes will be noted in the app's Play Store release notes.
