Overview
Time Machine ("the App") is a time-tracking application that includes a stopwatch, lap timer, countdown timer, bleep test, and a private, encrypted vault for storing your own files and media. Your privacy is built into the design: the App does not have an account system, does not connect to any servers, and does not collect, transmit, or sell any personal data.
Information We Do Not Collect
The App does not collect any personal information. Specifically:
- No account registration or sign-in is required or supported.
- No name, email address, phone number, or other identity data is collected.
- No location data is collected.
- No advertising identifiers are used, and no advertising is displayed.
- No analytics or usage-tracking SDKs are included.
- The App does not require the Internet permission and has no network access. Everything you enter or store stays on your device.
Data Stored on Your Device
All data the App creates is stored locally on your device. This includes your timer history, settings, and any files or media you place in the vault.
- Vault contents (files, photos, videos, notes) are encrypted and stored only on your device. The App never uploads or syncs them anywhere.
- Encryption keys used to protect your vault are held in the device's secure hardware-backed keystore and are protected by your device authentication (biometrics, PIN, or pattern).
- Settings and timing state are stored locally so the app can resume your stopwatch or countdown after the app is backgrounded or restarted.
Because this data never leaves your device, we cannot access it, recover it, or hand it over to anyone else.
Permissions Used
The App requests only the permissions it needs to function:
- Notifications — to show the ongoing timer notification while a stopwatch or countdown is running in the background, and to alert you when a countdown finishes.
- Foreground service — to keep timing accurate while the app is in the background or the screen is off.
- Vibration — to signal timer completion and bleep-test cues.
- Storage access — only when you choose files to add to your vault or export data; this is initiated by you through the system file picker.
These permissions are used solely for the features described. No permission is used for data collection.
Third-Party Services
The App contains no third-party analytics, advertising, tracking, or crash-reporting services. It does not communicate with any servers or third parties.
Children's Privacy
The App does not collect any personal information from anyone, including children under the age of 13. No special handling is required because no data is collected, transmitted, or shared.
Data Retention and Deletion
Since all data is stored locally on your device, you are in full control of it. Deleting the App from your device removes all data it created, including vault contents and settings. Uninstalling the App is the simplest way to delete all of your data. Within the App, you can also delete individual vault items at any time.
Security
Your vault is protected with strong, hardware-backed encryption on your device. Access to the vault requires your device authentication. While no method of electronic storage is 100% secure, we take reasonable measures to protect the data that never leaves your device.
Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Last updated" date at the top of this page. Since the App does not collect data, changes to this policy will not affect any data we hold about you.
