Privacy Policy

Effective date: November 2, 2026

StickrSnap ("the app") is made by Number29, LLC ("we", "us"). This policy explains what data the app collects, how it's collected, how it's used, and who it's shared with. If you have questions, email support@num29.com.

Summary

• To make a sticker, the photo you choose is sent to Google's Gemini AI service (Google LLC). The app asks your permission before it sends any photo.
• We don't store your photos on our servers. We don't sell your data, and we don't use it for advertising or tracking.
• You don't need an account. The app creates an anonymous account automatically to keep track of your tokens.

1. Photos you turn into stickers

What's collected: the photo you select and the art style you choose.

How it's collected: only when you tap Create Sticker or Remix, and only after you've agreed on the in-app "Before we make your sticker" screen. The app never reads your photo library except for the photo you pick.

How it's used: the photo is sent over an encrypted connection to our server (Google Cloud Functions for Firebase), which forwards it to Google's Gemini API to generate your sticker. The finished sticker is sent back to your device.

Who it's shared with: Google LLC, as the provider of the Gemini API. StickrSnap uses Google's paid Gemini API service. Under Google's terms for that service, Google doesn't use your photos or the generated stickers to improve its products. Google may keep them for a limited time to detect abuse and comply with the law. See the Gemini API Additional Terms of Service and Google's Privacy Policy.

Retention: we don't store your photo or the generated sticker on our servers. Stickers you save stay on your device: in Photos, and in the app's iMessage sticker drawer.

Your choice: you can withdraw permission at any time from Privacy & AI on the app's home screen. Without it, the app can't create AI stickers.

2. Account and token data

When you first open the app, it creates an anonymous account using Firebase Authentication. We store the following in Google Cloud Firestore:

• An anonymous account ID. It isn't your name, email, or phone number.
• Your token balance, free trials, and refund history.
• A record of each sticker generation: the style, remix level, AI model, time, whether it succeeded, and whether it was refunded. It doesn't include the photo or the sticker.
• Your referral code, and the referral code you used, if any.
• A random identifier attached to your in-app purchases, so a purchase can only be credited to your account.

We use this data to run the app: tracking tokens, crediting purchases and referral rewards, preventing abuse, and seeing which styles are popular so we can improve them.

3. Purchases

Purchases are processed by Apple. We never receive your payment details. When you buy tokens, the app sends us Apple's signed transaction record, which includes the product, transaction ID, and date. We use it to verify the purchase with Apple and add tokens to your account. We keep the transaction ID so the same purchase can't be credited twice.

4. Fraud and abuse prevention

• Apple App Attest and DeviceCheck: the app uses these Apple services to confirm requests come from the genuine app. DeviceCheck stores two yes/no flags per device with Apple: whether free trials were claimed, and whether a referral code was used. This prevents reinstalling the app to claim them again. We don't receive or store a device identifier.
• Firebase App Check: used together with App Attest to block requests that don't come from the genuine app.

5. Analytics

We use Google Analytics for Firebase to understand how the app is used, for example which styles are chosen, when stickers are saved or shared, and when errors occur. This includes app events, approximate location derived from your IP address, device and OS type, and an app-instance identifier. It isn't linked to your name or contact details, isn't used for advertising, and isn't used to track you across other companies' apps or websites.

6. Sharing

We share data only with the service providers that run the app:

• Google LLC: Gemini API, Firebase (Authentication, Firestore, Cloud Functions, App Check), and Google Analytics.
• Apple Inc.: in-app purchases, App Attest, and DeviceCheck.

These providers process data under their own privacy and security commitments, which give at least the same level of protection as this policy. We don't sell personal data or share it for advertising. We may disclose data if required by law.

7. Children

StickrSnap isn't directed at children under 13, and we don't knowingly collect personal data from them.

8. Your rights and deleting your data

You can ask for a copy of your account data, or ask us to delete it, by emailing support@num29.com with the Support ID shown at the bottom of the app's Invite Friends screen. Deleting the app removes the stickers and settings stored on your device.

9. This website

This website doesn't use cookies or analytics. It loads fonts from Google Fonts and a badge image from Product Hunt; those services receive your IP address when your browser loads them.

10. Changes

If we change what data the app sends to an AI service, or who it's sent to, the app will ask for your permission again. We'll post any changes to this policy on this page with a new effective date.
