Privacy Policy
Last updated: June 26, 2026
TandemlyHQ (“we,” “us,” or “our”) builds the “When did I last...” app. This policy explains what information we collect, how we store it, and your choices.
1. Information we collect
By default, the app stores your activity names, logs, notes, and settings locally on your device. We do not require you to create an account, and we do not collect this data by default.
If you contact us at support@tandemlyhq.com, we may keep the email and any information you provide so we can respond.
2. Optional Google Drive backup
If you choose to back up your data, the app creates a single file named when-did-i-last-backup.json in your own Google Drive. This uses Google Identity Services and the Google Drive API. The file is transferred over HTTPS and stored in your Google account. You can delete that file at any time from your Google Drive. We do not access the contents of the backup.
3. Premium purchases
On Android, premium purchases are processed through Google Play Billing via RevenueCat. We do not handle payment information directly. RevenueCat may process purchase tokens and device identifiers in accordance with its own privacy policy.
4. Analytics and notifications
The app does not use analytics or tracking. Local reminder notifications are scheduled and stored on your device only; no notification data is sent to us.
5. How we share information
We do not sell, rent, or share your personal information with advertisers. We only share information with third-party services when necessary to provide a feature you actively choose to use (Google Drive backup, Google Play purchase processing).
6. Data retention and deletion
Local data stays on your device until you delete it. You can delete all app data from the app settings. If you have backed up to Google Drive, you can delete the backup from your Google Drive. Emails sent to support@tandemlyhq.com are retained only as long as needed to resolve your request.
7. Children
The app is not directed to children under 13. We do not knowingly collect personal information from children under 13.
8. Changes to this policy
We may update this policy from time to time. The “Last updated” date at the top will reflect the latest version.
9. Contact us
