Memolens Privacy Policy
The whole policy in one sentence: Memolens collects nothing, and your photos never leave your device.
Effective date: October 11, 2026
Memolens has no account system, no analytics, no third-party SDKs, and no servers of ours to send anything to. The app reads your photo library to build a searchable index on your device, and that is where the index lives and dies. Whenever the app does use the network, it is talking to Apple, not to us: iCloud Photos delivering your originals, language downloads for on-device translation, and App Store purchases.
中文简述：Memolens 不收集任何数据。没有账号、没有统计埋点、没有第三方 SDK。照片的语义索引在你的设备上建立并保存，照片与索引数据永远不会离开设备。App 只会和 Apple 联网：iCloud 照片向设备传输原图、下载本机翻译用的语言包、App Store 内购，都不经过我们。
1. Who we are
Memolens is published by INVENTOWISE LLC, an independent software studio based in Amherst, New Hampshire, USA.
This policy governs the Memolens iOS app. The INVENTOWISE privacy policy governs inventowise.com, the website you are reading now.
2. What Memolens collects
Nothing. Concretely, Memolens has:
- No account system — there is nothing to sign up for
- No analytics or crash-reporting SDKs
- No advertising identifiers or trackers
- No third-party code that phones home
- No INVENTOWISE servers involved in running the app — we could not receive your data even by accident, because there is nowhere for it to go
The App Store privacy label for Memolens reads “Data Not Collected”, and this policy is the long form of that label.
3. What happens on your device
Memolens runs a machine-learning model on your device to read each photo and turn it into a compact numeric summary (an "embedding"). Searching and the app's memory features compare those numbers — that is the entire trick.
- The model ships inside the app and runs on your phone's own chip.
- The index — embeddings plus basic photo metadata such as dates and album names — is stored in the app's private container on your device.
- Your search history is saved on your device only, so recent searches can appear on the home screen. Long-press one to delete it, or clear all of it in Settings → Search history.
- On iOS 26 and later, a search typed in another language is translated with Apple's on-device translation before matching. The text you type is not sent anywhere.
- Memolens never uploads your photos or copies them out of your library. It changes your library only when you ask: deleting a photo from inside the app moves it to Recently Deleted, after iOS asks you to confirm.
4. Network connections, all with Apple
Memolens has no servers. It uses the network in three cases only, each between your device and Apple under Apple's privacy policy:
- iCloud Photos. If your library uses "Optimize iPhone Storage", some originals live in iCloud. When Memolens needs one, iOS fetches it through Apple's iCloud service, the same way the Photos app does.
- Translation languages. On iOS 26 and later, if you add a search language in the app's settings, iOS downloads that language for on-device translation. After the download, translation works offline.
- In-app purchase. Memolens offers a one-time purchase that unlocks every year of your library. Apple processes the payment; we never see your payment details or your Apple Account. The app keeps only Apple's confirmation of the purchase, on your device.
Nothing derived from your photos is transmitted anywhere by Memolens.
5. Permissions
Memolens asks for photo library access — that is the only permission it requests. Full access lets the app index your whole library, which is what makes search over all of your photos possible. If you grant access to only selected photos, Memolens indexes and searches just those. You can change this at any time in Settings → Privacy & Security → Photos.
6. Deleting your data
Because everything lives in the app's container on your device, deletion is entirely in your hands: delete the app and the index and search history are gone, while your photos stay untouched. To clear only your search history, use Settings → Search history in the app. There is nothing on any server to ask us to delete.
7. Children
Memolens does not collect data from anyone — including children. The app has no accounts and no chat. A photo leaves the app only if you tap Share and pick a destination in the iOS share sheet.
8. Changes to this policy
If a future version of Memolens ever changes what the app does with your data — for example, an optional online feature — we will update this policy before that version ships, and the change will be called out in the App Store release notes. The promise that your photos and index stay on your device by default is the product; we do not intend to change it.
