Stickerz turns your photos into WhatsApp sticker packs. The photos and the stickers stay on your device. There is no account, no sign-in, and no Stickerz server that your pictures are sent to.
Stickerz is developed by Tomer Glick. For anything in this policy, including a request about your data, write to happydays.contactus@gmail.com. For the purposes of the GDPR we are the data controller for the limited data described below.
None of this is transmitted to us. Deleting the app deletes all of it. Deleting a pack in the app deletes its stored photos.
Choosing a photo uses the system picker, so the app receives only the images you select and does not get access to your library as a whole.
Cutting the background out of a photo, and suggesting an emoji for a sticker, run on the device — Apple's Vision framework on iOS, Google's ML Kit on Android. The image is not uploaded for this. On Android, ML Kit may download a model file from Google Play services the first time it is needed; that download is a request for a model, not for your photo.
If you have device backup switched on, your app data can be included in it — iCloud Backup on iOS, Google's Android Backup on Android. That copy belongs to your Apple or Google account and is governed by their terms, not ours. On Android the app deliberately keeps this small and may include lower-fidelity copies of stickers rather than every original photo.
| What | Who receives it | Why |
|---|---|---|
| Ad requests: an advertising identifier, IP address (from which approximate location is inferred), device and app information, and whether you consented to personalised ads | Google (AdMob) | To select and show the banner and occasional full-screen ad that pay for the app |
| Usage events: fixed labels and counts — a screen was opened, a tool was used, a pack of n stickers was shared, an ad was shown — plus the standard information the Firebase SDK collects, such as app version, device model, OS version and country | Google (Firebase Analytics) | To see which parts of the app are used and where people get stuck |
| Crash and error reports: stack traces, device state and short English diagnostic strings such as "a sticker exceeded the size limit" | Google (Firebase Crashlytics) | To find and fix crashes and failed exports |
| A request for configuration values (how often an ad may appear, whether ads are on) | Google (Firebase Remote Config) | To adjust ad frequency without shipping an app update |
| Your finished sticker pack, when you send it | Because that is what the app is for. Once handed over, the pack is subject to WhatsApp's own privacy policy | |
| A problem report, only if you choose to send one | Whoever you send it to, through the system share sheet | To let you report a pack WhatsApp refused. See below for exactly what is in it |
What is deliberately not sent: your photos, your stickers, pack or publisher names, captions, emoji, accessibility descriptions, file paths, and any identifier that could tie a pack to you. Analytics parameters in this app come from a fixed vocabulary of labels and numbers; free-form text is never among them.
If WhatsApp refuses a pack, the app offers to build a report so the failure can be diagnosed. It contains facts about your pack rather than its content: how long the pack name is, whether it is plain ASCII, how many captions and emoji exist, image dimensions and byte sizes, and the limits that were breached. The pack name, publisher name and captions themselves are not in it. The encoded sticker images can be attached, but only if you tick that box — it is off by default. The report goes out through the system share sheet, so you choose its destination; nothing is uploaded automatically.
Ads are provided by Google AdMob. Google acts as an independent controller for the data it receives through ad requests; see Google's Business Data Responsibility page and its policy on how partner sites and apps use data.
Paid features are one-time, optional purchases made through the App Store (iOS) or Google Play (Android). Today there is one, the full Auto pack: every mood and full-size packs, with no ad to watch to make one. The app's other ads are unchanged by it. Apple or Google processes the payment under its own privacy policy; we never receive your name, payment card or billing address. The app asks the store only which of our products your account owns, keeps that answer on the device so the app works offline, and reports which product was bought — as a fixed label such as "auto_pack", never with a price, an order number or an account identifier.
Without the purchase, Auto pack's free packs each cost one rewarded ad that you choose to watch. It is served by Google AdMob exactly like the app's other ads, under the same consent described above. After the purchase Auto pack asks for no ad; the app's other ads continue as described above.
Data on your device stays until you delete the pack or the app. Data held by Google on our behalf is kept for the retention periods set in the Firebase console — crash reports for a limited window (Google's default is 90 days) and analytics events for the project's configured event-data retention. We do not keep any copy of it ourselves.
Depending on where you live, you may have the right to access, correct, delete or export your data, to object to processing, or to withdraw consent. Because the app holds no account and no directly identifying data, the practical routes are: delete the app to remove everything local, use the consent controls above to withdraw advertising consent, reset your advertising identifier, and write to happydays.contactus@gmail.com for anything else. If you are in the EEA or the UK you may also complain to your local data protection authority.
California residents: we do not sell or share personal information for cross-context behavioural advertising in the sense of the CPRA where consent has not been given, and the controls above are the way to exercise that choice.
Stickerz is not directed to children, and the app does not knowingly collect data from children. Ad requests are not tagged as directed to children or to users under the age of consent. If you believe a child has provided data through the app, write to us and it will be removed.
Photos and packs live in the app's private storage, which the operating system keeps separate from other apps. Data in transit to Google's services travels over HTTPS. No system is perfect, but the smallest surface is the strongest one: the app has no server of its own and no account to break into.
If this policy changes, the version at this address is updated and the date at the top changes with it. Material changes affecting advertising consent will be presented in the app through the consent form.
