Privacy policy

Last updated: 14 November 2026

Nutstash is an app for iPhone and Android that sorts your screenshots into topics and lists. It is made by gosu.team ("we", "our", "us"). This policy explains what the app does with your data, what leaves your phone, and how to delete it. Where the iPhone and Android apps work differently, each section says so.

1. Your photos and screenshots

Nutstash asks for access to your photos because neither iOS nor Android lets an app ask for screenshots alone. Once you allow it, the app looks only at screenshots. It does not open, read or analyse your other photos or videos. The screenshots stay in your photo library; Nutstash does not copy them, and nothing about them is sent to a server.

On iPhone

The app looks only at images that iOS marks as screenshots. For each one, it uses features built into iOS on your iPhone:

• Text recognition (Apple's Vision framework) to read the words on the screenshot.
• Image recognition (Vision) to describe what the picture shows, for example "a cat" or "a document".
• Apple Intelligence's on-device model, when available, to choose a topic and a short title. Nutstash does not use Apple's Private Cloud Compute or any other server for this.
• On-device translation (Apple's Translation framework), when a screenshot is in a language the model doesn't read. Language packs are downloaded by iOS from Apple; the text itself is translated on your iPhone.

On Android

The app looks only at images in your phone's Screenshots folders. On Android 14 and later you can instead allow access to selected photos only; Nutstash then sees just the ones you pick. For each screenshot, the app uses Google's on-device tools on your phone:

• Text recognition (Google's ML Kit, part of Google Play services) to read the words on the screenshot.
• Image labeling (ML Kit) to describe what the picture shows.
• Gemini Nano, Google's on-device model, on phones that support it, to choose a topic and a short title. It runs through Android's AICore system service on your phone; Android downloads the model from Google, and your screenshots are not sent anywhere to use it.

ML Kit and AICore process the images and text on your phone and do not send them or the results to Google. Like other apps that use them, they send Google technical metrics about how the tools perform: device and app details, a per-installation identifier, which feature ran and how long it took, the size of the input and output, model downloads and error codes. Google uses these for diagnostics and usage analytics, as described in Google's ML Kit data disclosure. They never include your screenshots or their text.

2. What the app stores

To show your topics, lists and search results, Nutstash keeps a small database on your phone with, for each screenshot:

• an identifier that points to the screenshot in your photo library, and the date it was taken;
• the text read from it, and, on iPhone, a translation when one was made;
• its topic, title, and names such as a film, book or place;
• what you did with it: done, dismissed, moved to the top, or moved to another topic.

The app also stores a few settings on your phone, such as whether you've finished onboarding and, on iPhone, whether check-in notifications are on.

This data is stored only on your phone. If you back up your phone (to iCloud or a computer on iPhone, or with Android's backup to your Google account), it is included in that backup the same way as other apps' data, under Apple's or Google's terms.

3. Notifications

On iPhone, if you allow notifications, Nutstash may send a reminder the day before a free trial ends, a note when a long sort finishes, and an occasional check-in that suggests one film, book, place or recipe you saved.

On Android, Nutstash shows a progress notification while it sorts a large batch of screenshots. It sends no other notifications yet.

All notifications are created on your phone. No notification content passes through our servers.

4. Subscriptions and payments

On iPhone, Nutstash Pro is sold through the App Store and Apple processes the payment under Apple's privacy policy. On Android, it is sold through Google Play and Google processes the payment under Google's privacy policy. We never see your name, Apple Account, Google Account or card details.

We use RevenueCat to check whether you have an active subscription. To do that, the app shares with RevenueCat:

• a random identifier created by the app, not linked to your name, Apple Account or Google Account;
• your purchase and subscription history from the App Store or Google Play (product, dates, renewal status, country and currency);
• basic technical information such as the app version, iOS or Android version and device model, and your IP address as part of the connection.

RevenueCat processes this on our behalf and may not use it for its own purposes. Nothing about your screenshots is shared with RevenueCat or anyone else.

5. Usage statistics and crash reports

This section applies to the iPhone app. The Android app does not send usage statistics or crash reports to us. If that changes, we will update this policy first.

To learn which parts of Nutstash are useful and to fix problems, the iPhone app sends anonymous usage events to PostHog, hosted in the European Union, which processes them on our behalf. An event says that something happened, for example that an onboarding screen was shown, the paywall was opened, the first sort finished and how long it took, a topic or search was opened, or a screenshot was marked done. Each event comes with:

• the same random identifier the app uses with RevenueCat (not linked to your name or Apple Account);
• counts, rounded into ranges where they could be revealing (for example "6–20 results");
• the topic name involved, such as "Movies & shows", and your plan (free, trial or Pro);
• technical details: app version, iOS version, device model, language, the country set in your iPhone's region settings, and whether on-device AI is available. Your IP address reaches PostHog as part of the connection, but it is not used to work out your location.

When the app crashes or freezes, iOS gives it a diagnostic report on the next launch; the app sends the type of problem and the app's own code locations involved, in the same way.

These events never include your screenshots, the text on them, titles or names read from them, or what you type into search. They are not used for advertising, not combined with data from other companies, and not used to track you across apps or websites. You can turn them off in Settings → "Share anonymous usage stats"; nothing is sent after that.

6. What we do not collect

Nutstash does not collect or receive your screenshots or their text, your other photos, your name, email address, phone number, contacts, location or advertising identifier. There are no advertising or cross-app tracking tools in the app.

7. How long data is kept

The database on your phone is kept until you delete the app; deleting the app deletes it. Deleting a screenshot from your photo library also removes it from Nutstash.

Purchase records are kept by Apple or Google and by RevenueCat for as long as needed to provide the subscription and as required by tax and accounting law.

Usage statistics and crash reports from the iPhone app are kept only as long as they help us improve the app. To have yours deleted, send us the Support ID shown in the app's Settings.

8. Children

Nutstash is not intended for children under 13, and we do not knowingly collect information from them.

9. Your rights

Depending on where you live, you may have the right to access, correct, export or delete personal data, to object to or restrict its use, and to complain to your data protection authority. Because almost all Nutstash data stays on your phone, you control it directly: deleting the app removes it. For subscription records or usage statistics, email [email protected] with the Support ID from the app's Settings (on iPhone) or your Google Play order number (on Android), and we'll handle it with RevenueCat and PostHog. We answer within 30 days.

10. Changes to this policy

If we change what the app collects or how it uses data, we will update this page and the date at the top. Significant changes will be announced in the app.
