1. Introduction
Lume is a task manager developed by Avery IO. We built Lume to be a local-first, private app — your tasks, categories and progress belong to you, and we deliberately do not collect, store or share your personal information. This policy explains exactly what happens with your data.
2. Information Collection and Use
Lume does not collect, store, or share any personal information. There is no app-level account, no sign-up, no login. Every task, category, completion, point total, rank and streak you accumulate is stored locally on your device.
If you choose to enable iCloud sync (see section 6), your data is mirrored through your own private iCloud database. It is never transmitted to a server operated by Avery IO, and we have no ability to read it.
3. In-App Purchases
Lume offers a single one-time, non-consumable in-app purchase called Lume Pro, which unlocks additional features. All purchases are processed exclusively by Apple through the App Store. Avery IO does not see, receive, or store your payment credentials at any point. Apple confirms only the entitlement (whether you have purchased Lume Pro) so that the app can unlock the corresponding features on your device.
4. Analytics and Usage Data
Lume does not include any third-party analytics SDK, telemetry library, or in-app tracking. The App Store privacy nutrition label declares "Data Not Collected", and that is literally the case.
Apple may, separately and only with your consent, provide developers with anonymous, aggregated metrics through App Store Connect — such as download counts, crash reports, and session counts. These reports contain no personally identifiable information and cannot be linked back to an individual user. You can opt out of sharing this data with developers at any time in iOS Settings > Privacy & Security > Analytics & Improvements.
5. Third-Party Services and Advertising
Lume does not display advertisements, does not use ad networks, and does not embed third-party tracking or marketing tools. The only external service Lume relies on is Apple's iCloud (CloudKit) for optional sync, and Apple's StoreKit for processing the in-app purchase — both of which are governed by Apple's own privacy policy.
6. iCloud Sync and Data Storage
iCloud sync is an optional feature you turn on in Settings. When enabled, your tasks, categories and progress are mirrored through your personal iCloud private database — bound to your own Apple ID — so the same data is available across your devices.
The private database is, by design:
- Inaccessible to Avery IO — we cannot view, query, or recover its contents.
- Inaccessible to Apple's staff — Apple encrypts it in transit and at rest.
- Free of any app-level account or identifier — sync uses your Apple ID directly.
You can turn iCloud sync off at any time. Any data already on a device remains on that device. If you use the in-app "Wipe all data" option while sync is enabled, the deletion is mirrored to iCloud and to any other device signed into the same Apple ID — there is no separate iCloud backup. For a portable copy of your data you can keep independent of iCloud, use the Export feature in Settings > Backup.
7. Children's Privacy
Lume is rated 4+ and is suitable for all ages. Because the app does not collect any personal information from any user, it does not knowingly collect personal information from children under 13. If you believe a child has somehow provided personal information through the app, please contact us so we can address it.
8. Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes to the app or to clarify our practices. When we do, we will update the "Effective" date at the top of this page. We encourage you to review this page periodically.
