Privacy and biometric notice
Last updated
Fitcut measures faces and reads hair, so we hold ourselves to a stricter standard than most apps. This page says exactly what happens to your photo and your data, in plain words.
The short version
- Your face is measured on your device. The 478-point mesh never leaves it.
- Your selfie is never stored at rest. At most, it's held encrypted for 24 hours while your previews render.
- Previews, measurements and answers delete themselves after 30 days.
- Google processes your photo (Anthropic only if we switch Claude on, fal only as a fallback). Nobody buys it.
- No face templates, no training on your photos, no session replay on sensitive screens.
- You can delete everything right now, from this page.
1What we collect and where it's processed
We only collect what we need to recommend haircuts and render the previews you ask for. The measuring of your face happens on your device; the rest happens on our servers and our processors’ servers.
| Data | Processed | Why |
|---|---|---|
| Face mesh (478 landmarks) | ProcessedYour device only | WhyTo measure proportions. Never sent to us. |
| Face proportions | ProcessedOur server | WhyUnitless ratios (like length ÷ width), their percentiles and photo-quality flags. Used to rank cuts. |
| Your front photo | ProcessedOur server and processors, in memory | WhyRe-encoded on your device to at most 1092 px with location data removed. Used to read your hair and to render previews. |
| Hair traits | ProcessedOur server | WhyTexture, density, hairline range, cowlicks and similar, each with a confidence level. |
| Quiz answers | ProcessedOur server | WhyHow much you'll cut, styling time, trims and the like. Used to rank cuts. |
| Previews | ProcessedOur processors, then private storage | WhyThe images you asked for, labelled “AI preview”. |
| ProcessedOur server | WhyRequired to see your results: we email you your results and a link back to them, so you can open them on any device (and your barber card, if you have one). If a partner shop referred you, it keeps that referral with you. Marketing email only if you tick the separate box. | |
| Payment | ProcessedStripe | WhyCard details go to Stripe, never to us. |
2Biometric notice and consent
Some US states treat face geometry, and photos used to derive it, as biometric identifiers or biometric information. We treat all of it that way, wherever you live.
- What: the face proportions derived from your photo, and the photo itself while it is being analysed and used for previews.
- Why: only to recommend haircuts and to render the previews you request. Nothing else.
- Consent first: before the camera opens, we ask you to confirm you are 18 or older, to give written consent to this processing, and to confirm the photo is of you or that you have the person’s consent.
- How long: as set out in the retention schedule below. Everything is permanently destroyed on that schedule, or sooner if you delete it, and never later than 30 days after your last analysis. The photo itself is never kept longer than 24 hours.
- No sale: we never sell, lease, trade or otherwise profit from your biometric data.
- Disclosure: only to the processors listed below, only to perform the service, or where the law requires it.
- Security: encrypted in transit and at rest. A photo held for rendering is encrypted with AES-256-GCM.
- Withdrawing consent: delete your data with the button below, or email us. Withdrawing stops all further processing of your photos and measurements. It doesn’t cancel a membership: billing continues until you cancel it (one click, from your account).
3Retention schedule
A deletion job runs every day and removes anything past its date.
| What | Kept for | Details |
|---|---|---|
| Your photo (selfie) | Kept forNever stored at rest | DetailsProcessed in memory and discarded once your analysis and previews finish. The only exception: so your previews can render, the photo is held as an encrypted file for at most 23 hours and deleted automatically within 24 hours, whatever happens. |
| Face mesh (478 points) | Kept forNever leaves your device | DetailsComputed in your browser to measure proportions. We never receive it. |
| Previews of you | Kept for30 days | DetailsStored privately, then deleted automatically. |
| Measurements, hair profile and answers | Kept for30 days | DetailsYour face proportions (ratios only), the hair traits read from your photo, your quiz answers and your ranked results. |
| Your email | Kept for30 days, with your results | DetailsKept with your analysis to send your results and open them on your other devices, then deleted with it. Longer only where it's needed: on an order (financial records), with a partner shop's referral (12 months), or, if you opted into marketing emails, until you unsubscribe (after that only on our do-not-email list). |
| Orders | Kept forKept (financial records) | DetailsProduct, amount, date and payment status. No images attached. |
| Your agreement to automatic renewal | Kept forAt least 3 years | DetailsWhen you join, the exact renewal terms you ticked to agree to, their version, the plan and when, with a random browser ID. The law asks us to keep this record. No photo, no IP address. |
| Anonymous aggregates | Kept forKept | DetailsCounts such as which cuts people pick, published only for groups of 20 or more. No images, no landmarks, nothing that points to you. |
| Barbershop referral link | Kept for12 months | DetailsIf a partner shop's QR or link brought you here, which shop it was, so the shop gets its share of what you buy. |
