Publisher: Boss Computing Ltd Version: 1.1 · Effective: 20 September 2026
Everything you type into Anker stays on your device. There is no account, no sign-in and no sync. We never receive it, never store it, and cannot see it. We could not retrieve it for you if you asked, and we could not delete it for you either — only you can, from within the app or by deleting the app.
The only information that reaches us is anonymous technical data about how the app itself is behaving: crashes, performance and aggregate usage counts. None of it contains anything you entered.

For the limited technical data described in section 3, we are the data controller.

Everything you create in Anker — lists, entries, notes, images, and any text you type — is stored locally on your device only. It is never transmitted to us.
We have no server holding your content, no database of users, and no means of accessing your device. If you lose your device, or delete the app, that content is gone and we cannot restore it.
Depending on your iOS settings, app data may be included in your device's own backups, including iCloud backups. Those backups are handled by Apple under Apple's terms, not ours, and we have no access to them.
Anker uses Google Firebase to collect anonymous technical telemetry:
| What | Why |
|---|---|
| Crash reports (Firebase Crashlytics) — the point in the code where a crash occurred, device model, OS version, app version | So we can find and fix crashes |
| Performance data (Firebase Performance Monitoring) — app start time, screen rendering times | So we can find and fix slowness |
| Aggregate usage counts (Firebase Analytics) — app opens, app version in use, broad device and region information | So we know which versions are in use and whether the app is working |
| An app instance identifier — a random identifier generated by Firebase for your installation | So separate crash reports from one installation can be grouped together |
This data is not linked to you. We do not collect your name, email address, phone number, contacts, location, photos, or anything you have entered into the app. We do not set a user ID. We do not attach any of your content to any crash report or analytics event. We do not use this data for advertising, we do not sell it, and we do not share it with anyone beyond the processor named below.
The app instance identifier is reset if you delete and reinstall the app.
Our lawful basis for processing the technical data in section 3 is legitimate interests (UK GDPR Article 6(1)(f)) — specifically, our interest in keeping the app working and fixing faults. We have considered the impact on you and concluded it is minimal, because the data is anonymous, limited to the app's own behaviour, and cannot be connected to you or to anything you have written.
Google Ireland Limited / Google LLC, as the provider of Firebase, acting as our processor. Firebase may transfer data outside the UK, including to the United States, under Google's standard contractual clauses and its participation in the EU–US and UK extensions of the Data Privacy Framework.
Google's privacy information for Firebase: https://firebase.google.com/support/privacy
We use no other processors, no advertising networks, and no third-party analytics beyond Firebase.
Crash and performance data are retained by Firebase according to Google's default retention periods — currently up to 90 days for crash reports and up to 14 months for aggregate analytics. We do not retain copies outside Firebase.
Content on your device is kept until you delete it. We never hold it at all.
Under the UK GDPR and the Data Protection Act 2018 you have rights to access, correct, erase, restrict and object to the processing of personal data about you, and to data portability.
In practice there is very little for those rights to attach to here: we hold no content and no identifying information, so we are generally unable to connect any request to a particular person's data. We will always respond and explain what we hold.
To exercise any right, or to object to the processing in section 3, contact [email protected].
You can also stop the telemetry entirely at any time by deleting the app.
You have the right to complain to the Information Commissioner's Office — https://ico.org.uk — though we would appreciate the chance to help first.
Anker is not directed at children and we do not knowingly collect any information from them.
If we change this notice we will update the version and date below and publish the revised version at this address. Material changes will also be surfaced in the app.
