Hairfit Privacy Policy

Last updated November 3, 2026

Hairfit shows you a new haircut or hair color on your own photo before you visit a salon. This policy explains what the app and its server handle, why, and for how long. The short version: no account, no advertising, no tracking, and your selfie is deleted from our server as soon as your look is made.

No account

Hairfit does not ask for your name, email address, phone number or Apple ID. On first launch the app creates a random identifier and keeps it in your iCloud Keychain. It is sent with each request so the server knows how many looks you have left. It is not linked to your identity.

Your selfie

• When you create a look, the app sends a reduced copy of your selfie (about 1,000 pixels wide), the style and color you picked, and the hair type you chose, to our server.
• Our server passes the photo to Google's Gemini API, an AI image service, which returns the edited photo. Google processes it under the Gemini API Terms for paid services, which do not allow Google to use it to improve its products. Google may keep it for a limited time to detect abuse, as described in those terms.
• The app asks for your permission before the first photo is sent, and names Google as the service it is sent to. You can withdraw permission at any time in Settings.
• Our server never writes your selfie or the result to disk or to a database. Both exist only in memory while your look is being made and are discarded as soon as the result is returned to your phone.
• Your original selfies and your saved looks are stored only on your iPhone, inside the app. They stay there until you delete them or the app.

Face data

To check your framing and work out your face shape, Hairfit uses Apple's on-device Vision framework to find your face and measure its proportions (for example the width of your jaw and cheekbones). This happens entirely on your iPhone. The measurements and face landmarks are never sent to our server or anyone else, are not stored, and are never used for advertising, marketing, identification or data mining.

Purchases

Looks and Hairfit Plus are bought through Apple's App Store. Apple processes the payment; we never see your card or Apple ID. The app sends us Apple's signed record of the purchase so we can add looks to your balance.

What we keep

For each device identifier we keep your look balance, your subscription status and a record of each look added or used (date, amount and reason). We keep no record of which photos you used or how your looks turned out.

What we do not do

• No advertising, analytics or tracking SDKs, and no tracking across apps or websites.
• We do not sell or share your information, except with Google to create your looks and with Apple to process purchases.
• We do not look at your photos.

Security

All traffic between the app, our server and Google is encrypted (HTTPS).

Age

Hairfit is for people aged 18 and over. It is not directed at children and does not knowingly collect information from anyone under 18.

Your choices

Delete any look or selfie in the app at any time. Settings → Delete all my data removes every photo and look from your phone and deletes your device record and history from our server.

Changes

If this policy changes, the new version will be posted here with a new date.
