Privacy policy
Your scans stay on your iPhone.
In short: Follicl has no accounts and no servers that hold your photos. Your scans, and everything the app works out from them, are stored and processed on your iPhone. We don't run analytics, show ads, track you across apps, or sell data. The only data that leaves your device is what's needed to process a subscription purchase, and that goes through Apple and our payments provider, RevenueCat.
This policy explains how the Follicl iOS app ("Follicl", "we", "us") handles information. It covers the app and this website.
Photos and scan data
When you take a scan, Follicl uses your iPhone's camera to capture photos of your hairline from several angles. The app then analyzes those photos on your device to line them up and trace your hairline, so that different scans can be compared.
These photos, and everything derived from them (hairline traces, hair outlines, alignment data), are saved in Follicl's private storage on your iPhone. We never upload them to Follicl or anyone else.
Face data
To frame each scan the same way every time, Follicl uses:
- the TrueDepth camera to capture depth information alongside your photos;
- on-device face detection and face landmark models (Apple's Vision framework and Google's MediaPipe, both running locally) to find the position and angle of your face and hairline.
This face data is used only to guide your capture and align your scans for comparison. It is:
- processed entirely on your iPhone;
- stored only inside the app on your device, alongside the scan it belongs to;
- never sent to us or to any third party;
- never used to identify you, for advertising, or for marketing;
- never used to train models.
It is deleted when you delete the app.
Treatments, reminders and settings
Your treatment log, dose check-ins, reminder schedule, onboarding answers and app settings are also stored only on your device. Reminders are local notifications that your iPhone schedules itself. No server is involved.
Subscriptions
Purchases are handled by Apple through your Apple ID. We never receive your name, email, or payment details.
We use RevenueCat to manage subscription status. RevenueCat receives:
- a random, anonymous app user ID (not tied to your name, email, or Apple ID);
- your purchase and subscription details (product, price, dates);
- basic technical information such as your iOS version, app version, country or region, and IP address.
This is used only to confirm and restore what you've paid for. None of it is linked to your scans.
Backups
If you've turned on iCloud Backup or back up your iPhone to a computer, iOS may include Follicl's data in those backups. Backups are managed by Apple under Apple's privacy policy and your own device settings. We don't have access to them.
What we don't do
- No account or sign-in.
- No analytics, crash-reporting or advertising SDKs.
- No tracking across other companies' apps or websites, and no advertising identifier.
- No selling or sharing of personal information.
Deleting your data
Because your data lives on your iPhone, you control it. Deleting Follicl removes all of its data from your device, apart from any copies in backups you've made yourself.
To have your RevenueCat purchase records deleted, email us and we'll pass the request on. Apple's own purchase history is managed through your Apple ID.
Children
Follicl isn't directed at children under 13, and we don't knowingly collect information from them.
Your rights
Depending on where you live (for example under the GDPR or CCPA), you may have the right to access, correct or delete personal information, or to object to how it's processed. We hold almost nothing about you, but if you'd like to make a request, email us and we'll respond within 30 days.
Medical disclaimer
Follicl is a photo tracking tool. It isn't a medical device and doesn't diagnose, treat or predict any condition.
Changes
If we change how Follicl handles data, for example by adding optional cloud backup, we'll update this page and change the effective date. If a change is significant, we'll also tell you in the app before it takes effect.
