Stickture Privacy Policy

Effective date: 14 September 2026 · Applies to the Stickture Android app (app.stickture.app) and stickture.app.

Who we are

Stickture is an Android app that turns your photos into WhatsApp-ready stickers using AI. This policy explains exactly what data the app processes, why, and what happens to it. Contact for anything privacy-related: support@stickture.app.

Your photos

When you tap Generate, the photo you picked and your chosen style options are sent over an encrypted connection to our backend, which passes them to our AI provider, OpenAI, solely to generate your stickers. OpenAI acts as a data processor on our behalf for this single purpose: your photos are not used for advertising, not sold, and not shared for any other purpose. We do not keep a copy of your photo. The finished sticker is returned to your device right away; we also keep a copy on our servers for up to a day in case delivery needs to be retried, then delete it automatically. Rejected generated images and stickers you report are kept longer, as explained under Generation quality and Reporting a sticker. Your sticker library is stored on your phone. If Android's backup is switched on for your device, your stickers are included in that backup — it goes to your own Google account, not to us, and we cannot see it.

Backups

Backups. Android can back up apps automatically to your Google account. If that is switched on for your device, your Stickture sticker library is included. That backup belongs to you: it is stored in your Google account under Google's terms, it is encrypted, and Stickture cannot read, download or delete it — only you can.

To turn it off, open your phone's Settings → Google → Backup and either switch backup off or exclude Stickture. To delete a backup you already have, open the Google One app → Storage → Backups, pick the device, and delete it. Your credit balance is deliberately excluded from backup and never restores onto a new device.

Device ID, credits, and purchases

Stickture gives every device 12 free stickers. To make that work — and to stop the same device claiming free stickers forever — we store, in our database (Google Firebase / Google Cloud, region us-central1, United States):

• a one-way hashed identifier of your device (we can't reverse it into anything that identifies you personally),
• your credit balance, and
• purchase records for credit packs (Google Play's purchase token, which product you bought, and its status).

We use this data for exactly two purposes: fraud prevention (one free grant per device, refund abuse detection) and purchase fulfillment (adding the credits you bought, restoring them, and removing credits from refunded purchases). Credits belong to the device, not to a person or account.

No accounts, no personal details

There is no sign-up. We do not collect your name, email address or contacts, and the app never asks for your location. Usage statistics do carry an approximate location (country or city) that Google derives from your IP address; see Usage statistics and crash reports in the app. The app uses an anonymous session identifier from Firebase purely so your device can talk to our backend securely.

Payments

Credit-pack purchases are processed by Google Play's billing system. Google handles your payment method and billing details under Google's Privacy Policy; Stickture never receives your card or bank information — we only receive confirmation that a purchase happened so we can add your credits.

Website analytics

Our website, stickture.app, uses Google Analytics, a service provided by Google, to understand how people find and use the site. Google Analytics sets cookies in your browser and collects information such as the pages you view, the links you click (for example, the Google Play button), your approximate location (country or city, derived from your IP address), and your browser and device type. We look at this data only in aggregate — to see whether the site is doing its job — and we do not use it to identify you. It is never linked to anything the Stickture app stores.

Google processes this data on our behalf under Google's Privacy Policy; you can read more about how Google uses it at policies.google.com/technologies/partner-sites. To opt out, use the Google Analytics opt-out browser add-on or block cookies for stickture.app in your browser settings.

Usage statistics and crash reports in the app

The app sends anonymous usage statistics to Google Analytics for Firebase, a service provided by Google, so we can see which parts of the app get used and where it fails. This is on unless you switch it off. Nothing is sent until you have seen the switch. A new install shows it on the "Before you start" page during setup; an existing install shows it once, in a notice after the update. After that it lives under Preferences → Privacy as "Share anonymous usage statistics and crash reports".

An event records which screen you are on and what you did there: for example, whether a pack was requested, made, saved, shared or added to WhatsApp; whether the credits screen was seen and which credit pack, if any, was bought; and whether a sticker was reported, with the reason category only. Google's own SDK records a completed purchase as well. Each event also carries a random per-install identifier that Google generates, the app version, your device model, OS version and language, and an approximate location (country or city) that Google derives from your IP address.

An event never contains your photo, your captions, your corrections, the hashed device ID, your support code or anything you type. We never attach a user ID to it, and we never use it to identify you.

We never use any of it for advertising and never sell it. The app does not collect the Android Advertising ID, we have switched off Google signals and ads personalisation, and we have not linked Analytics to any advertising product. The app's statistics and the website's visit counts land in the same Google Analytics property. Nothing joins the two, because the app has no account or user ID and Google signals are off.

Google keeps event-level usage data for 2 months. Aggregate totals, such as how many packs were made in a week, stay in our Analytics reports for as long as we keep the property.

Switch it off and the app stops collecting, erases the analytics identifier on your phone and deletes any crash reports it has not sent yet. Switch it back on later and Google issues a fresh identifier. Delete my data does the same and also clears your choice, so you see the switch again before the app sends anything.

Crash reports. If the app crashes, a report goes to Firebase Crashlytics, Google's crash-reporting service, so we can find and fix the cause. A report contains the stack trace, what the app was doing at the time, device details (model, OS version, memory) and an installation identifier that Google generates. It never contains your photo or captions. Crash reports follow the same switch as usage statistics, so off means none are sent. Google keeps crash data for 90 days.

Google processes this data on our behalf under Google's Privacy Policy and explains how it handles it at policies.google.com/technologies/partner-sites.

Google Play's rating card

In this version, the app can show Google Play's own rating card once, after your second successful sticker pack. Anything you type there goes to Google Play under Google's terms, not to us; the app never sees it. You can also open our Play listing any time from Preferences → About → Rate Stickture.

Generation quality

To diagnose failed stickers and avoid unnecessary replacements, the app sends our backend technical details about generation: whether you requested a retry or correction, whether the app replaced a failed sticker automatically, which earlier generation it relates to, the app version, and the results of image-quality checks. These checks measure things such as transparent corners, visible image coverage and artwork touching a crop's edge.

When a generated image fails a check, we keep the generated sheet and its rejected sticker crops privately for up to 30 days so we can review and fix the problem. These are generated images, never the original photo you selected. This operational diagnostic data goes to our backend and is separate from the optional Google Analytics and crash reports. It contains no caption or correction text. If a diagnostic upload cannot finish, the app may keep a pending copy on your phone for up to seven days and try again. Delete my data clears pending copies and deletes retained diagnostic images associated with your device.

Reporting a sticker

If you report a generated sticker as inappropriate, we store the report with the prompt parameters that produced it (the mood, style, and caption options) so we can investigate and improve our safeguards. So we can review what you reported, we keep a copy of that generated sticker for up to 90 days, then delete it automatically. The report never includes the original photo you started from.

How long we keep data

The device record (hashed ID, credit balance, purchase records) is kept for as long as it is needed to provide the service and prevent fraud — in practice, for the life of the app on your device and a reasonable period afterwards. Sticker reports are kept only as long as needed to review them. Rejected generated images are retained for up to 30 days; operation records are held in our backend for 30 days, and technical operation history is also kept in our private monitoring system to diagnose service problems. Google keeps event-level usage statistics for 2 months and crash reports for 90 days; aggregate totals stay in our Analytics reports for as long as we keep the property. If we delete data on request (below), it is removed from our live database immediately and from backups in the normal backup cycle.

Deleting your data

Open Preferences → Privacy → Delete my data in the app. That deletes your device's record — the hashed device ID, its credit balance, and its purchase records, including generation diagnostics and retained rejected images — and removes every sticker and pending diagnostic upload from your phone. Deleting also removes any remaining credits, and the free 12-sticker grant cannot be claimed again on that device. It also stops usage statistics and crash reports, erases the analytics identifier on your phone, deletes any crash reports not yet sent and clears your choice, so you see the switch again before the app sends anything. Statistics already sent carry nothing we can tie to you, so we cannot pick yours out; they expire at Google on the schedule above.

If you no longer have the phone, email support@stickture.app and include the support code shown on that same screen, so we can find the right record. Uninstalling removes the library from your phone. If Android backup is on, a copy may remain in your Google account until you delete it there — see Backups above.

Children

Stickture is not directed at children under 13, and we do not knowingly collect data from children under 13. If you believe a child has used the app and you would like their device record removed, contact support@stickture.app.

Changes to this policy

If we change this policy, we will post the new version at this address and update the effective date at the top. Material changes (for example, collecting a new type of data) will also be highlighted in the app before they apply to you.
