Privacy Policy
「Last time」 is a fully local tool for tracking when recurring things last happened. We take your privacy seriously. This app has no internet access, requires no account, collects no personal information, and contains no ads or third-party analytics SDKs.
1.We collect no personal information
- This app does not request the INTERNET permission, so it is technically unable to upload your data to any server;
- No sign-up or login is required, and we do not collect your name, phone number, email, device identifiers, location, or any other personal information;
- There are no advertising or analytics SDKs and no usage tracking;
- All data is stored solely in the app's private storage on your device.
2.Data stored locally and how it is used
To provide the tracking features, the following data is stored only on your device:
- Item details: name, icon, color, opacity, note, and reminder settings;
- Records: the timestamp and note of each entry;
- Item background images you pick from your gallery or take with the camera, stored as files in the app's private directory;
- App settings: sorting, theme, language, display preferences, and auto-backup settings.
Uninstalling the app removes all of this data. You can also delete any item (together with its full history) at any time within the app.
3.Permissions
The app uses only the following permission, only when you need it:
| Permission | Purpose | Required? |
|---|---|---|
| Post notifications (POST_NOTIFICATIONS) | Delivering local reminders you have set for items | No — only if you use reminders, and granted at your discretion |
- No storage permission: export/import and backup use the system file picker (Storage Access Framework), and gallery images are chosen through the system Photo Picker;
- No camera permission: photos are taken by your device's system camera app and saved only into the app's private directory. The app never scans or reads other content in your gallery.
4.Export, backup, and sharing (initiated only by you)
- You can manually export your data as a backup file (JSON), a spreadsheet (CSV), or a monthly report (PDF), save it to a location you choose, or share it through the system share sheet;
- If you enable auto-backup, the app only writes backup files into a folder you have selected, on the schedule you set;
- These files are entirely under your control and are never uploaded or sent to any third party by this app. Please safeguard any exported files containing your personal records.
5.Feedback and crash logs
- Feedback: when you choose to send feedback, the app opens the email app on your device and it is entirely up to you whether to send it. The email contains only what you write, plus your device model, OS version, and app version to help diagnose issues;
- Crash logs: if the app crashes, a crash log (device model, OS version, app version, and error stack trace) is generated locally. It stays on your device and only leaves it if you manually choose to report it by email. You can delete the log at any time in Settings.
6.Children's privacy
This is a general-purpose productivity app not directed at children, and it collects no personal information from anyone. Minors are advised to use it under the guidance of a guardian.
7.Third-party services
This app includes no third-party SDKs and shares no data with third parties. System apps you use while exporting, sharing, or sending feedback (file managers, email apps, etc.) are provided by their respective vendors and governed by their own privacy policies.
8.Changes to this policy
If this policy changes, we will notify you within the app or in the release notes. Significant changes will be presented prominently.
