The apps: your questions answered

On the App Store for iPhone at https://apps.apple.com/us/app/facesearch-ai/id6792020218 and on Google Play for Android at https://play.google.com/store/apps/details?id=com.humanityfounders.facesearch. Both are published by Humanity Founders. The store links also sit in the footer of every page on this site.

No. Sign in to the app with the account you use on the website, by email and password, Google or Apple, and your plan, your normal and deep credits and your saved scans are there. A credit spent on the phone is one fewer on the website, and the other way round.

A plan bought inside the app is charged by Apple or Google, at the store's local price, which can differ slightly from the website price because of regional pricing and taxes. A plan bought on the website is charged by card through the billing page. Either way the plan works on both the app and the website.

In your App Store or Google Play subscription settings, not in FaceSearch. The plan stays active until the end of the period you paid for. Refund requests for app purchases go to Apple or Google under their own rules. Deleting your FaceSearch account does not cancel a store subscription, so cancel first.

Yes, and it is the app's best use. Most apps block saving other people's photos, so take a screenshot of the profile or post, crop it in the phone's photo editor so one face fills most of the frame, and pick it from the camera roll. The photo tips page explains what makes a photo match well.

Access to the photo you pick, so it can upload it for the search. It does not need your location, contacts or microphone. The photo is checked and re-encoded on the server with its metadata stripped, used for your search only, and never used to build a face database, exactly as on the website.

Yes. Saved scans belong to your account, not to the device, so a scan kept on the phone shows in History on the website and vice versa. Delete a scan in either place and it is gone from both. Searches run without signing in are not saved anywhere.

Yes, from the account section in the app, or from Profile on the website, or by following the steps on the delete your account page. Deletion removes the account, its saved scans and its data. Cancel any store subscription first, because deleting the account does not stop the store from billing.
