Privacy Policy
Last updated: 29 September 2026
- Polished is for people aged 13 and over. We don't allow anyone under 13 to create an account.
- We collect only what the app needs to work. We don't sell your data, show ads, or track you across other apps or websites.
- Photos of your hand are private to you. We remove location details from them, and you can delete them at any time.
- Some features use AI from Anthropic (Claude) and OpenAI. We tell you when you're talking to AI.
- You can delete your account, and everything in it, from inside the app: Me → Delete my account.
Who we are
Polished ("we", "us") is a nail design app. You can contact us about privacy at privacy@trypolished.app.
What we collect, and why
| What | Why |
|---|---|
| Your email address | To sign you in with a one-time code. We don't send marketing emails. |
| Your first name | To greet you in the app, and so friends know whose poll they're voting on. |
| Your date of birth | To make sure you're 13 or older and to give people aged 13 to 17 the teen version of Polished. It can't be changed later, and nobody else can see it. |
| Photos of your hand (only if you add one) | To show designs on your own hand. Stored privately, so only you can see them, until you delete them. We remove location and camera details from every photo. |
| Designs you save, notes you write, your polls and their votes | So you can keep your favourite looks, share them with your nail tech, and see what your friends picked. |
| What you do with designs (saves, try-ons, "Not for me") and the style choices in your Taste Profile | To show you designs you'll like on Home. You can see this in Me → Taste Profile, reset it, or turn personalisation off. |
| Reports you send | So we can remove anything harmful. |
| Daily usage counts | To keep AI features fair and affordable (for example, a daily limit on Stylist messages). We count messages; we don't keep your Stylist conversations. |
We don't collect your contacts, your precise location, advertising identifiers, or anything from other apps.
Live try-on with your camera
Live mode in Try on uses your camera to find your hand and paint the design on your nails as you move. This all happens on your phone: the camera picture is never recorded, stored or sent to us or anyone else. If you tap the shutter button, the photo is saved only on your phone until you choose to share it.
AI features
Polished uses AI to help design nails:
- Stylist and Design Studio send what you type, and the design you're working on, to Anthropic (Claude) to suggest designs.
- Hand photo check: when you add a hand photo, it is sent to Anthropic to check that it shows only a hand. Photos that don't pass are never stored.
- Painting nails on a hand sends the hand photo and the design to OpenAI, which returns the edited picture.
- Short comments on adults' polls are checked by OpenAI's moderation service before your friend sees them.
These companies process this information to provide the feature to us. Under their business terms, they don't use it to train their AI models, and they keep it only for a limited time (for example, to prevent abuse).
Friend polls
When you share a poll, anyone with the link can see the poll's question, the designs (including your hand photo, if you used it), and your first name. Poll links are hidden from search engines and stop working a week after voting closes. Deleting the poll removes it straight away.
Friends who vote don't need an account. We store their vote, any reaction or comment, and a random code kept in their browser so each phone votes once. We don't collect voters' names or contact details. Anyone can report a poll from the voting page.
Teens (ages 13 to 17)
People aged 13 to 17 get extra protections:
- Accounts are always private.
- Friends can only send kind preset reactions on teens' polls. No typed comments.
- No public posting, and no messages from strangers.
- The same data protections as everyone: location removed from photos, hand-only checks, and reporting everywhere.
Children under 13
Polished is not for children under 13. Anyone who enters a date of birth under 13 can't create an account, and we don't knowingly collect personal information from children under 13. If you believe a child under 13 has given us information, email privacy@trypolished.app and we'll delete it.
Who we share data with
We never sell your data. We share it only with the companies that run parts of Polished for us, and only what each one needs:
- Supabase: our secure database, file storage and sign-in.
- Anthropic and OpenAI: the AI features above.
- Resend: sends your sign-in code emails.
- Cloudflare: hosts this website and the poll voting pages.
- Apple: delivers the app (and test versions through TestFlight).
We may also share information if the law requires it.
How long we keep it
We keep your information while you have an account. You can delete hand photos, saved looks, polls and your Taste Profile history at any time in the app. When you delete your account, we delete your account and everything in it, including photos, straight away.
Security
Your data is stored with Supabase and protected so each person can only reach their own information. Hand photos are kept in private storage and shown only through links that expire after an hour. No system is perfectly secure, but we work to protect your information.
Your choices and rights
- See and change your Taste Profile, or switch personalisation off: Me → Taste Profile.
- Delete a hand photo: Try on → Photo → Your hand → bin icon.
- Delete your account and all your data: Me → Delete my account.
- For a copy of your data, or any other privacy request, email privacy@trypolished.app.
Changes to this policy
If we make important changes, we'll tell you in the app before they take effect. The date at the top shows when it was last updated.
