Privacy Policy

App: Sticker Lab Effective: July 28, 2026 Last Updated: July 28, 2026

Sticker Lab ("the App", "we", "us", "our"), operated by Tranquil Mind Technology JSC, respects your privacy. This Privacy Policy explains what information we collect, how we use and share it, and the choices and rights you have. By using the App, you agree to this Policy.

Sticker Lab is a sticker maker that turns your photos into custom stickers using on-device AI background removal and an editor, and lets you organize them into packs and share them to messaging apps. You do not need to create an account to use it.

On-device photo processing. The photos you pick or capture are edited locally on your device — including the AI background cutout. We do not upload your photos or the stickers you create to our servers. They leave your device only when you choose to share or export them to another app (for example WhatsApp, Telegram, or the system share sheet).

1. Information We Collect

We do not ask you to fill in forms or sign in, so we do not collect names, email addresses, or contacts. The App and the third-party services listed in Section 3 automatically collect a limited set of technical data that leaves the device:

We do not collect your photos, your stickers, your contacts, your microphone audio, or your precise location.

2. How We Use Information

We use the information above to:

3. Third-Party Services

The App uses the following third-party SDKs/services, which may receive the data described above. Each processes data under its own privacy policy:

Advertising consent (UMP / IAB TCF). In regions where consent is required (such as the EEA and the UK), the App presents a consent prompt (via Google's User Messaging Platform and the IAB Transparency & Consent Framework) before personalized ads are shown. On iOS, the App also asks for App Tracking Transparency permission. You can change your choice at any time — see Section 7.
Resetting or limiting your advertising ID. You can reset or delete your advertising ID, or opt out of ad personalization, in your device settings: on Android, Settings → Privacy → Ads; on iOS, Settings → Privacy & Security → Tracking / Apple Advertising.

4. How We Share Information

We do not sell your personal information for money. We share the limited data described above with the third-party services in Section 3 so they can provide advertising, analytics, attribution, crash reporting, and payment processing on our behalf or for the advertising purposes you have consented to. We may also disclose information where required by law, to protect our rights or users' safety, or in connection with a merger, acquisition, or sale of assets.

U.S. state privacy note. Some U.S. state laws (e.g. California's CCPA/CPRA) define "sale" or "sharing" broadly to include the use of identifiers for cross-context behavioral (personalized) advertising. To the extent our use of advertising identifiers for personalized ads qualifies as "sharing" under those laws, you can opt out by declining ad-personalization consent, by resetting/limiting your advertising ID (Section 3), or by contacting us (Section 12).

6. Data Retention

We and our partners keep data only as long as necessary for the purposes above or as required by law. Advertising and analytics identifiers are retained according to each partner's retention schedule; crash and diagnostic data are kept for a limited period to investigate stability issues.

7. Your Rights

Depending on where you live, you may have the right to access, correct, delete, port, or restrict the processing of your personal data, to object to processing, and to withdraw consent.

Because the App has no accounts, we may not be able to identify your data on our own. When you contact us to exercise a right, please include your device's advertising ID (and, if relevant, your approximate purchase date) so our partners can locate and act on the data. You can also exercise ad choices directly via the device settings in Section 3. Contact us at contact@tranquilmind.co.

8. Children's Privacy

The App is intended for users aged 13 and older and is not directed to children under 13 (or the minimum age of digital consent in your country). We do not knowingly collect personal data from children under that age. If you believe a child has provided data through the App, contact us at contact@tranquilmind.co and we will take appropriate steps to delete it.

9. International Data Transfers

Your data may be processed in countries other than your own, including the United States, where our service providers operate. Where required, we and our partners rely on appropriate safeguards (such as the European Commission's Standard Contractual Clauses) for these transfers.

10. Data Security

We use encryption in transit (HTTPS/TLS) and reasonable technical and organizational measures to protect your data. However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

11. Changes to This Policy

We may update this Policy from time to time. Material changes will be posted on this page with a new "Last updated" date. Your continued use of the App after changes take effect constitutes acceptance of the updated Policy.
