Summary
Blotty hides faces, text, numbers, license plates and other details in your photos and videos — entirely on your iPhone. Your photos, videos and everything you do with them stay on your device. Nothing is uploaded, and no server ever sees your content.
Blotty has no accounts and does not ask for your name, email or phone number. The only information that leaves your iPhone is anonymous technical data — app events with the country they came from, crash and error reports — and the subscription check with Apple and RevenueCat. It is not linked to who you are. Blotty contains no advertising, does not track you and does not sell any data.
Information Processed
Your photos and videos. Processed only on your device. Blotty sees only the photos and videos you pick in the system picker and has no access to the rest of your library. It saves a new edited copy and never changes or deletes your originals.
Detections and edits. The faces, text, numbers, plates and codes Blotty finds, the text it reads and the areas you hide are processed only on your device and never sent anywhere.
Saved copies. A saved copy contains only the edited picture (and, for videos, the sound if you keep it). It leaves out location (GPS), date and time taken, camera and device details, depth data and the video part of Live Photos.
My Data. The details you add to My Data are stored only on your iPhone, in the iOS Keychain, protected with Face ID or your passcode and never synced to iCloud or anywhere else. Face ID is handled by iOS; Blotty never receives your face data.
Local data. Your settings, hiding styles and presets, and an anonymous app user identifier are stored on your device. How many of the free tries you have used is kept in the iOS Keychain on your iPhone — only counts, nothing about your photos — so that reinstalling the app does not reset them. Temporary working files are deleted when no longer needed.
Purchase data. Apple processes all purchases through the App Store. Apple and RevenueCat process product, purchase, subscription status and receipt information to unlock and restore Blotty Pro, under an anonymous app user identifier. We never receive your payment details, name or email.
Analytics and diagnostics. PostHog receives anonymous technical data: when the app is installed, updated, opened or closed; when photos or a video are saved and how many, when the subscription screen is shown and from where, and when the app asks for an App Store rating; how many presets and My Data entries you have (never what they contain) and whether you have Blotty Pro; crash reports; and, when an operation fails, the type of error and technical facts about the file involved (such as format, size, dimensions, duration or codec — never the file itself or its name). This comes with your iPhone model, iOS version, app version and language. App events also include the country they were sent from, which PostHog works out from the network (IP) address; crash and error reports include no location. RevenueCat also sends PostHog your subscription events, such as a purchase, renewal or cancellation. All of it is linked only to a random identifier created by the app, not to your identity. IP addresses and any location more precise than the country, such as the city, are not stored. Blotty never sends screenshots, screen recordings, taps, your photos or videos, detections, recognized text, My Data or anything you type.
Support. If you email us, we receive your email address and what you write. The email prepared from the app’s Settings includes your anonymous app user ID in the subject so we can find your purchase.
Permissions
Blotty asks only for what it needs to work:
- Choosing photos and videos — no permission needed. You pick them in Apple’s system picker, which gives Blotty only the items you select. Blotty cannot read the rest of your library.
- Photos: “Add Photos Only”. Needed to save edited copies to your library. It lets Blotty add new photos and videos, but not see, change or delete the ones already there. Without it, Blotty cannot save to your library.
- Face ID. Used to open My Data. iOS checks your face (or passcode) and tells Blotty only whether it succeeded.
Blotty does not ask for access to your camera, microphone, location, contacts, full photo library or for permission to track you. You can change these permissions at any time in iOS Settings → Blotty.
How We Use Information
To provide editing and saving; to unlock, validate and restore Blotty Pro; to monitor crashes and errors and improve stability; to understand, in aggregate, how the app is used and in which countries; and to answer your support requests. We do not use your content to train machine-learning models.
Sharing
We use these services, each under its own terms and privacy policy:
- Apple — App Store, payments;
- RevenueCat — subscription status;
- PostHog — anonymous app events, crash and error reports (hosted in the EU).
We do not sell, rent or share information with advertisers, ad networks or data brokers, and we do not track you across other apps or websites. Because your photos, videos and My Data never leave your device, we have nothing of them to share.
International Transfers
Our service providers may process the anonymous technical and purchase data described above outside your country, with safeguards where required.
Retention
Your photos, videos, settings and My Data stay on your device until you delete them or the app. iOS may keep the encrypted My Data entry in the Keychain after the app is deleted; Blotty erases it the next time it is installed. To remove My Data at once, delete the entries in the app first. The count of free tries used stays in the Keychain after the app is deleted, and a new installation continues from it.
Anonymous analytics, crash reports, purchase records and support emails are kept only as long as reasonably necessary for the purposes above.
Your Choices
You choose which photos and videos Blotty sees. You can delete My Data entries in the app, turn off Face ID for Blotty in iOS Settings, manage or cancel your subscription in your Apple Account settings, or delete the app at any time. For any privacy question or request, write to us at the address below.
Children and Minors
Blotty is suitable for all ages and has no accounts or age verification. It does not collect personal information from anyone, including children. Users under the age of majority should use the app and make purchases only with a parent’s or guardian’s permission.
Changes
We may update this policy. Material updates will change the effective date and may be announced in the app or on this page.
