Privacy

Yowl is operated by EO Ventures LLC, which is responsible for the information described in this notice. Contact us at hello@yowl.lol.

Yowl does not require a user account or password. We process information when you post, react, pay, or contact us. Messages and display names you post are public, along with their amounts and placement on a board.

What we store

• Your message. The text you wrote, the name you typed on it, what you paid, which side you backed, and when. The name is just a label — anyone can type any name, and it is not checked against anything.
• Your age confirmation. That you ticked it, when, and the exact wording you were shown.
• Stripe references. The checkout session and payment identifiers for your payment, so a refund can find the right message.
• A one-way fingerprint, for reactions. Reacting is free, so to stop one person mashing the button we store a salted SHA-256 hash of your IP address and browser user-agent. This is a pseudonymous identifier, not a guarantee of anonymity. It is never attached to your public message.
• A rate-limit counter, keyed by a salted hash of your IP address.

What we never have

Your card number, expiry or security code — those go to Stripe and never touch our servers. We also run no analytics, no advertising pixels and no third-party trackers, and we set no cookies to follow you.

Who else your data reaches

• Stripe takes the payment. Stripe collects your card details and whatever contact details it asks for at checkout, under its own privacy policy. Our Stripe account can provide access to payment information and the customer contact details collected at checkout, including information needed to handle refunds and disputes.
• Anthropic. Before you are charged, your message text is sent to Claude to be screened against the rules. That is how a message that breaks them is refused before it costs you anything. Only the message text is sent by our screening code, not your separate handle or payment details. Anything you include in the text is part of that submission.
• Supabase hosts the database, and Vercel runs the site. Hosting and service logs may contain technical request information.
• Support email. When you contact us, we and our email providers process your email address, message, and any details you send so we can respond.

Nobody buys this data from us, because we do not sell it, rent it, or share it for advertising.

Kept in your browser, not by us

Your own reactions and the last name you used are stored in your browser so the buttons look right when you come back. The site reads these saved values. When you submit a message or reaction, the relevant handle or reaction is sent to our server. Clearing your site data removes the local copies, not records already held on the server.

How long we keep it

Published messages and their reactions remain available as board history while the board is published, unless removed. You can request removal using the contact address below. Payment and age-confirmation records are kept separately from public visibility for handling refunds, disputes, fraud prevention, and accounting obligations. We do not automatically erase those records when a message comes down.

Rate-limit identifiers become eligible for deletion after their window is more than 24 hours old; our scheduled cleanup normally runs every five minutes. Cleanup can be delayed during an outage. Browser-saved preferences stay until you clear them. Support correspondence is kept while needed to resolve your request and any related payment or legal issue. We review retained records and delete information that no longer serves these purposes. Our providers manage their own records and backups under their policies.

If you want your message taken down, or the record of it removed, email hello@yowl.lol and we will do it. We aim to respond within one business day. Some payment records have to be kept regardless, because Stripe and tax rules require it — a takedown removes the message from the board, not the fact that a payment happened.

Children

Yowl is for adults. You confirm you are 18 or older when you pay, and if a payment was made on your card by someone under 18 in your household, email us and we will refund it. No proof required.
