Privacy Policy

Last updated 27 August 2026 (rev. g) · Yellow8 Studios LLC

1. What stays on your device

This is the part most design tools cannot say, so it goes first.

• Your boards. Everything you make is saved in your own browser, on your own device. We never receive it and cannot see it. That also means we cannot recover it — if you clear your browser data it is gone, so export anything that matters.
• Your uploaded pictures. A photograph you add is read by the page and stays there. Nothing uploads it.
• The background remover. Crevano removes backgrounds by running the model on your machine. The model file is served from crevano.app, is cached by your browser, and does its work in the page. Your picture is never transmitted, to us or to anyone else — and the remover is the same on the free plan and the paid one, so paying does not buy a better one or a different one. The single exception in the whole app is Refine edge, a separate button covered in section 2: it is the only thing that sends a picture anywhere, and only at the moment you press it.
• Your date of birth. The signup form asks for it, works out your age in your own browser, and sends us only whether you are 13 or over. The date itself is never transmitted and never stored.

2. Refine edge — the one time a picture leaves your device

Refine edge is a paid tool for difficult cutouts — hair, fur, flyaway strands — where the on-device model is not good enough. It works by asking a better model, which we do not run ourselves, for a cleaner edge. We would rather state exactly how that works than describe it vaguely.

• It happens only when you press Refine edge. Never automatically, never in the background, never on a picture you have not chosen.
• What is sent: that one picture, as a PNG, shrunk to no more than 1024 pixels on its longest side. Nothing else travels with it — not your name, not your email address, not your account, not your board, not the other pictures on it.
• Who receives it: fal.ai, which runs the model. fal stores the inputs and outputs of requests made to it under its own privacy policy and retention rules, which are theirs and not ours.
• What comes back: a grayscale mask — a black-and-white picture of which parts are the subject and which are the background. Your picture's colors are recombined with that mask on your own device.
• What we keep: nothing of the picture. It passes through our server and is not written to any disk or database of ours. What we do record is that a refine happened, against your account, so the monthly allowance can be counted.

If you would rather no picture ever left your device, simply do not use Refine edge. Everything else in Crevano, including background removal, works without it.

3. Your account

Accounts are optional. You can open Crevano, build a board and export it with no account at all. When you do make one, we hold:

• Your email address, and the six-digit sign-in codes we send to it. There is no password, so there is nothing here to steal or reset.
• Your session — a token stored in your own browser that keeps you signed in, and which your browser sends back when you use a paid feature.
• Your subscription status — whether a plan is live, and when it renews or lapsed.
• Counts of paid usage — how many Refine edge calls you have made this minute and this month, against your account. Numbers only; no pictures.
• Confirmation that you are 13 or over — a yes or no, nothing more.
• Where you heard about us, if you picked something from the list.
• A record of your agreement to our terms: the date, and which version of the wording you agreed to.
• The country your request came from, which our host reports automatically. Not your address, and not your IP address.

4. Anonymous counters

Crevano records a small number of counts about what a browser is capable of — whether it can run the background-removal model, roughly how fast, roughly how much storage it will allow. We use it for one decision: how many people can get the free on-device remover instead of needing a paid one.

These counts carry no identifier whatsoever. No account, no cookie, no session, no IP address, no browser string, no graphics-card name. Each row is a handful of coarse buckets and one duration, and there is no field in it that could be linked back to a person or to another row. They are stored on our own hosting; no analytics company is involved.

5. Feedback you send us

If you use the feedback form to send a suggestion or report a problem, we store what you wrote and email it to our support address. That includes the message itself, the address you gave us to reply to if you gave one, a short technical note about your browser, and the country your request came from. Send us only what you are happy for us to keep.

6. Payments

Paid plans are handled by an outside payment processor. We never see or store your card number — it goes to the processor, not to us. We are told only whether your subscription is live. The processor will be named here, with a link to its own privacy policy, before any payment is taken.

7. The companies that touch your data

The complete list, and what each one does:

• Cloudflare — hosts the site and runs the small server pieces behind it, and stores the sign-up and usage counters described above.
• Supabase — holds accounts: your email address, sign-in codes, sessions and subscription status.
• Resend — sends our email.
• fal.ai — runs the Refine edge model, and only on a picture you explicitly send it. See section 2.
• Google Fonts — our pages load two typefaces from Google's font service, which means your browser makes a request to Google to fetch them. Google receives that request in the ordinary course of serving a file.

Each of these processes your information on our instructions, for the purpose described, and for nothing else.

8. Email we send you

By setting up an account you agree to receive email from us. There are three kinds, and that is the whole list:

• Your sign-in code and occasional notes about the app itself — new element packs, changes worth knowing about.
• A request for an honest review of the app, and of the book if you bought it. Honest is the operative word: we are asking for your real opinion, whatever it is. Nothing is ever offered in exchange for a review, and no discount or benefit depends on you leaving one.
• Discount offers on future books and products.

Every email has an unsubscribe link. Use it and we stop, without affecting your access to the app.

9. We do not sell your information

We do not sell, rent, trade or otherwise pass your personal information to third parties for their own use. The only companies that touch it are the ones listed in section 7, and they process it on our instructions only.

We do not use your boards, your uploaded pictures or anything you write to train any machine-learning model, and we do not license them to anyone else who would.

10. Tracking

No advertising pixels, no analytics profile, no third-party trackers following you around. We set no cookies for advertising or measurement.

11. How long we keep it

Account details: until you ask us to delete them, or until the service closes down. Usage counts: they roll over each month and are kept only long enough to enforce the allowance and check our own bills. Feedback: until we have dealt with it and for a reasonable period afterward. Pictures sent to Refine edge: we keep none, and fal's retention is governed by fal's policy.

12. Your choices

Write to [email protected] and we will, without argument:

• tell you exactly what we hold about you;
• correct anything that is wrong;
• delete all of it;
• stop emailing you.

13. Children

Crevano is not intended for children under 13 and we do not knowingly collect information from them. The signup form checks age before asking for an email address. If you believe a child under 13 has given us their details, write to us and we will delete the record.

14. Changes

If we change this policy we will update the date at the top. If the change is a significant one, we will email you about it.

15. Who we are

Crevano is run by Yellow8 Studios LLC. Questions, complaints and deletion requests all go to [email protected].

This policy is written in plain English by the people who built Crevano, so that you can actually check it against what the software does. It is a description of our practices, not legal advice, and we are not lawyers.
