PerfectBrows needs one thing from you: a photo of your face. There is no account, no ads and no tracking. Because that photo is a selfie and not a picture of a room, this page is explicit about what happens to it — including the parts that are less than obvious.
PerfectBrows asks for no sign-up, no email address and no name. The app signs in anonymously to Firebase, which issues a random identifier so your analyses can be returned to your device. That identifier is not linked to you, and we hold no name, email, phone number or address.
When you ask for an analysis, the photo you took or chose is uploaded to our Firebase Storage bucket (Google Cloud, United States) and then:
Your original photo is deleted automatically 30 days after upload by a scheduled job. The generated result stays in your library until you delete the app or ask us to remove it.
We do not run face recognition and we do not build a face template, a faceprint or any biometric identifier. The model reads shape and proportion to produce a cosmetic suggestion, and nothing about your face is used to identify you or matched against any other photo.
Images are delivered to the app over public storage.googleapis.com links. The address of each file contains your random identifier and a random analysis identifier, so it cannot be guessed or browsed, and it is not listed anywhere. But it is not password-protected: anyone who obtains the exact link can open the image, and the link does not expire.
In practice the link is only ever sent to your own device. Still, these are photos of your face, so treat a PerfectBrows image link the way you would treat any unlisted link to a personal photo — if you share it, whoever receives it can keep opening it. If you would rather your selfies were not handled this way, please do not upload them.
Subscriptions are sold and processed by Apple through your Apple Account. RevenueCat, our purchase-infrastructure provider, receives an anonymous app-generated identifier and receipt information to confirm whether your subscription is active. PerfectBrows never sees your payment details. See RevenueCat's privacy policy.
PerfectBrows uses Firebase Analytics and Crashlytics to count anonymous events (which screens are opened, whether an analysis succeeded) and to receive crash reports. These carry no photo content and no personal identifiers. See Firebase's privacy documentation.
If you turn on "notify me when it's done", the app schedules a local notification on your device. No push server is involved and no notification data leaves your phone.
PerfectBrows shows no advertising and performs no cross-app or cross-site tracking. We do not request App Tracking Transparency permission, because we do not track.
Deleting the app removes your anonymous identity from your device, which means the analyses stored under it can no longer be reached from the app. To have the stored photos and records erased from the server as well, email eacompany947@gmail.com from the device in question and say so; we will delete them.
PerfectBrows is not directed at children and collects no personal information from anyone.
