Blurize
Privacy Policy
Welcome to Blurize ("we," "our," or "us"). Your privacy is critically important to us. This Privacy Policy explains how we collect, use, and protect your information when you use our mobile application.
This policy is designed to comply with global privacy regulations, including but not limited to the General Data Protection Regulation (GDPR) (Europe), California Consumer Privacy Act (CCPA) (US), Children's Online Privacy Protection Act (COPPA) (US), and Kişisel Verilerin Korunması Kanunu (KVKK) (Turkey).
1. 100% On-Device Processing
The core functionality of Blurize is to blur faces and objects in your photos and videos. We are committed to your privacy:
No Media is Uploaded. All face scanning, detection, video processing, and exporting happen 100% offline locally on your device's hardware. Your photos and videos are NEVER transmitted to, stored on, or processed by our servers or any third-party servers. Your media remains strictly on your device.
1a. Face Data
Blurize uses on-device detection to help you find and blur faces and license plates in your own photos and videos. We want to be explicit about how this works:
- What we detect: Using Google ML Kit's on-device face detection, the app locates the position of faces (bounding-box coordinates) within the media you choose. A separate on-device model locates license plates the same way — only their position, never the characters on them. The app does not create faceprints, face-recognition templates, or any biometric identifier, and it does not identify or recognize who anyone is.
- How it is used: Face and plate locations are used solely to let you select what to blur or cover, and to render the blurred output — entirely on your device.
- Sharing: This data is never shared with us or any third party. It never leaves your device. It is not sent to our servers or to any server, because Blurize has no media backend.
- Storage & retention: When you scan a photo or video, the face and plate positions found are saved on your device, inside that project, so you can close the app and come back to your edits. Projects live in the app's private storage, which is excluded from device backups. Deleting a project deletes its face and plate data; deleting the app deletes all of it. No face data is stored in any account, database, or backend.
- Audio: If your video has sound, Blurize may check on your device whether the audio contains speech, and the optional voice changer alters the pitch of that audio. This happens only on your device, nothing is recorded or uploaded, and Blurize never uses the microphone.
In short: face and plate positions are created and kept only on your device, inside your projects, to power the blur feature — never collected by us, never shared, and deleted with the project.
2. Information We Collect
Because your media is processed offline, we only collect minimal data necessary to maintain app functionality and provide personalization:
A. Authentication Data
We use Firebase Anonymous Authentication to create an anonymous session for you. Signing you in this way requires no name, no email address and no other personally identifiable information. Blurize has no user accounts.
B. App Preferences and Settings
We use Firebase Remote Config and Firebase Cloud Firestore to deliver app-wide configuration (for example, video length limits and feature switches) that is the same for every user. Your own choices — a project's blur style, selected faces and other edits — are stored only on your device, inside the project. We also use Firebase App Check to confirm that requests to these services come from the genuine Blurize app.
C. Analytics and Usage Data
We use Google Analytics for Firebase to understand how users interact with our app. This includes:
- App launch frequency
- Screens visited
- Anonymous device information (OS version, device model)
- General usage patterns
D. Crash and Error Reports
We use Firebase Crashlytics to collect crash reports if the app encounters an error. These reports include technical device information and stack traces but do not contain your personal photos or videos.
E. Payment and Subscription Data
If you purchase premium features, payments are processed securely through your app store (Apple App Store or Google Play) and managed via RevenueCat. We do not collect or store your credit card information. We only receive an anonymous user ID and your subscription status.
F. Advertising Data
The free version of Blurize displays advertisements served by Google AdMob. Premium subscribers do not see ads. To deliver and measure ads, Google and its partners may collect and process certain data, including:
- A device advertising identifier (e.g., Google Advertising ID or Apple IDFA)
- IP address and approximate (non-precise) location
- Device and connection information (device model, OS version, language)
- Ad interaction data (impressions, clicks)
Depending on your region and your consent choices, ads may be personalized (based on the data above) or non-personalized (contextual only, with limited data used for frequency capping, fraud prevention, and reporting). We never share your photos, videos, or any media with advertising networks — your media is processed entirely on your device and is never accessed for advertising. For more on how Google uses this data, see How Google uses information from sites or apps that use our services.
G. Support Requests
If you use Report a Problem in the app, we send your message together with your device model, OS version, app version and your anonymous support ID. You may also enter an email address. That field is entirely optional — the report is sent with or without it, and we ask for it only so we can reply to you. If you provide one, it is stored with your report and used solely to respond to you; it is never used for marketing and never shared. Your photos and videos are never included in a report. Reports, including any email address you gave, are deleted automatically 30 days after they are sent.
3. How We Use Your Information
The minimal data we collect is used solely to:
- Provide, maintain, and improve the application.
- Personalize your app experience.
- Monitor app stability and fix crashes.
- Process your in-app purchases and manage your subscription.
- Analyze anonymous usage trends to improve future features.
4. Third-Party Services
We use the following third-party services, which may collect anonymous data as described above. We encourage you to review their privacy policies:
- Google Firebase (Auth, Firestore, Remote Config, App Check, Crashlytics, Analytics): Google Privacy Policy
- Google AdMob (Advertising): Google Privacy Policy
- RevenueCat: RevenueCat Privacy Policy
- Apple / Google (Payment Processing): See their respective store privacy policies.
5. GDPR, CCPA, KVKK, and Global Privacy Rights
Depending on your location, you have rights under regulations like the GDPR (EU), CCPA (California/US), and KVKK (Turkey). Because we use Anonymous Authentication, we hold very little that identifies you: we never ask for your name, and the only personal data we may hold is an email address you chose to give us in a support request (see 2.G). Your data footprint is minimal. You have the right to:
- Access: Request a copy of the limited telemetry/settings data associated with your anonymous ID.
- Rectification: Correct any inaccurate settings data.
- Erasure ("Right to be Forgotten" / Deletion): You can delete your projects in the app at any time. On Android, deleting the app or clearing its data also removes the anonymous Firebase ID. On iOS, the system may keep that anonymous ID on the device after the app is deleted, so reinstalling on the same device can restore it. To have any data linked to your ID deleted — analytics, crash reports, a support request and any email address you gave with it — contact us with the support ID shown on the Account screen, and we will delete those records.
- Opt-Out (Do Not Sell or Share My Info): We do not "sell"
your personal information for money. Under certain laws (such as the CCPA), the
use of advertising identifiers for personalized advertising may be considered
"sharing." You can control this:
- Advertising consent (EU/UK): Where required, we (via Google's consent tools) ask for your consent before serving personalized ads, and you may withdraw it.
- Limit ad tracking: On iOS, you can deny App Tracking and reset your advertising identifier in Settings → Privacy & Security → Tracking. On Android, you can opt out of ad personalization and reset your Advertising ID in Settings → Google → Ads.
- Analytics/Crashlytics: Analytics and crash reports contain no photos, videos or name and are linked only to your anonymous ID. Analytics does not use your advertising identifier, and its data is not used for advertising, unless you allow tracking on iOS. You can turn usage statistics off at any time in the app under Account → Share usage statistics; crash reports have no separate switch. Deleting the app stops both, and to have what was already collected removed, contact us with your support ID.
Which personal data is processed, for what purposes and on what legal grounds, to whom it is transferred, and how to apply under KVKK Article 11 is also set out in the Information Notice.
6. Children's Privacy (COPPA)
Blurize does not knowingly collect personally identifiable information from children under the age of 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us at support@blurize.app. Since we use Anonymous Authentication, we cannot easily identify users, but we will take steps to delete any associated backend data if notified.
7. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. If we make material changes, we will notify you by updating the "Effective Date" at the top of this policy or by displaying a notice within the app.
