Privacy Policy

What Palettero is

Palettero is a free tool for choosing and exporting color palettes for websites. It does not require an account.

What stays in your browser

Your palette, fonts, style, template choice and project text are saved as a draft in your browser (localStorage) so a reload brings your design back. Drafts are stored only on your device, never sent to a server, and you can clear them by choosing Start over in the editor or by clearing your browser's site data.

Share links

If you click Share, the design (colors, fonts, style, template and the project text you typed) is saved on our database, run by Supabase, under a short random link so anyone with the link can open it. Do not include personal or confidential information in the project text. Links are not listed or indexed. We do not link them to you, because Palettero has no accounts.

Accounts and saved designs

You do not need an account to use Palettero. If you create one, you can sign in with Google, GitHub or a link sent to your email. We receive your email address and, from Google or GitHub, your name and profile picture. Sign-in is handled by Supabase, our authentication and database provider.

When you click Save, the design (colors, fonts, style, template and the project text you typed) is stored on our database under your account. Only you can read, change or delete your saved designs; they are not listed publicly. You can have up to 50.

You can delete your account at any time on the Account page. That permanently removes your saved designs, your profile and your sign-in. Backups at our provider may keep copies for a short period.

Live links

If you are signed in you can create a live link. It shows your design, and every change you make while the link is live, to anyone who has the link, until it expires or you revoke it. Revoking erases the design from the link. A live link shows your name only if you tick that box, and never your email address. Live links are not listed or indexed.

Sign-in cookies

If you sign in, Palettero sets cookies that keep you signed in. They are strictly necessary, are not readable by scripts on the page, and are removed when you sign out. A few short-lived cookies also exist during the sign-in itself. Your editor draft is kept in your browser's local storage, not in a cookie.

Website screenshot analysis & AI vision

When you upload website screenshots in 'Start from my site', color roles, contrast and style estimates are measured entirely on your device inside your browser. Screenshots and cropped images are stored locally on your device (IndexedDB) and are never stored on our servers.

If you explicitly consent to analyze layout and typography with AI, reduced copies of your screenshots (and the text visible in them) are sent to an AI vision service (Google Gemini, or Cloudflare Workers AI as a fallback). On Google's free tier, submitted content may be processed under Google's terms. A 'Colors only' option is always provided so you can use the feature without sending any data off your device.

Palette suggestions and third-party AI providers

If you click Suggest palettes, the project name and description you typed are sent to a third-party AI provider to generate color suggestions. Today that is Google (Gemini) or Groq. If neither is available, suggestions are generated on our server from keywords and nothing is sent to a provider.

Text is sent only when you click the button. The provider handles it under its own terms and privacy policy, which may include retention and review, so do not include personal, confidential or sensitive information.

To save cost, suggestions and ratings are cached on our servers for up to 7 days. The cache key is a one-way hash of the request, with no account, email or IP address attached, and the same request from anyone gets the same stored answer. Snapshot share links are cached for a day, because they never change.

Feedback and the waitlist

If you send feedback, we store the message, its type, the page path you were on (never your design), the reply email if you give one, and your account id if you are signed in. If you join the waitlist, we store your email and the optional line you write. We use these only to run the beta. You can ask us to delete them at any time using the contact address below.

Who can see account data

The people who run Palettero can see account email addresses, the names and dates of saved designs, usage counts and feedback, and use that to operate the service: to apply limits, answer questions and deal with abuse. Admin actions are logged.

Technical data

Our hosting provider, Cloudflare, processes requests to deliver the site and may log technical data such as IP address and browser type. We use your IP address briefly to limit how often the suggestion feature can be used. We do not use it to identify you.

Cookies and tracking

Palettero does not set advertising or tracking cookies. The only cookies are the sign-in cookies described above. When switched on, we use Cloudflare Web Analytics, which is cookieless and anonymous: it counts page views and does not follow you across sites or identify you. There are no other trackers.

Your choices

You can use Palettero without suggestions by skipping that step. You can delete your account and saved designs yourself on the Account page, or ask us to delete any data we hold about you using the contact address below.

Changes and contact

We will update this page when the product changes, and the date below will change with it.
