Privacy

What Yoink stores

• Your wallet address, when you sign in. Signing in is a signature, not a transaction, and costs no gas.
• A sign-in session: a random id in a cookie on your browser, kept in our database with your wallet and the time you signed in, so you stay signed in for up to 30 days. Sign out deletes it at once. A session you never sign out of stops working after 30 days, and its record stays with us.
• Your profile, if you make one: your username, your picture and your bio. All of it is optional. We also count how many pictures you upload each day, to stop abuse.
• Who you follow.
• Reports you send about another wallet, with the reason you picked and any note you wrote.
• App reports: the app you reported, the reason you picked, and your note and contact details if you give any. Your wallet and your IP address are not kept with it, even when you are signed in.
• Pictures you add for a token or collection, and the names, descriptions, traits and links you give it, from before it launches. Also a log of each picture we check: your wallet, the file name, the time, its size, fingerprints of the picture and whether we accepted it.
• Token and collection info: the picture, description and links a creator sets for a launched token or collection, and a list of every change to them with the wallet that made it. Each change after launch is kept with the signature that approved it.
• Picture reports: the reason you picked, and your note and contact details if you give any. If you are signed in, your wallet is kept with the report. When the picture already has an open report for the same reason, yours is counted on that one, and your note, contact details and wallet are each kept only if it had none.
• Moderation records: when Yoink hides a profile or a game, removes a profile or frees a name, a private record of what was done, when and why. For a freed name, the record keeps the name. When Yoink takes down a picture, a record of that too, and lists of blocked pictures and of wallets that can no longer add pictures for tokens or collections.
• Your usage and AI cost logs: your plan and top-ups, and a record of each AI step you run (what kind of step, what it cost us and when).
• Your payments: for each top-up or Yoink pass you pay for, your wallet, what it bought, the price, the network, the token and the amount you sent, the transaction's id and the time. A top-up or pass Yoink gives you is kept the same way, with the owner wallet that gave it. A payment Yoink could not add, because it was less than the price, is kept too: your wallet, what it was for, the amount, the price and the time, until it is made right.
• Test ETH from Yoink: when Yoink's faucet sends you test ETH, the wallet it went to, how much, the transaction and the time, and a scrambled code made from your connection's address (never the address itself), so one network cannot ask again and again.
• Your Used list: a row for each send of yours to an app on Yoink once the chain confirms it, with what the chain records about that send: your wallet, the app, the action, the amount, the network, the transaction and the day. Anyone can point us to a send by its transaction id, and we keep only what the chain records about it. Only you can read your list, on your page.
• Pictures made for your page: when the builder makes a picture for your page, we keep the picture, your wallet, which page asked for it, the service that made it and what it cost, and when it was made, last used and published. A picture no page has used for 30 days, and that was never published, is deleted.
• Page views: for each published app, one number, how many times its page was opened. Nothing about who opened it.
• What you build: the games you launch, the records of your launches, and each version of an app you publish, with its files, its description and what you asked the builder for.
• Your wishes: when your idea asks for something Yoink cannot build yet and you pick a way to get close, your idea, the part that cannot be built and the way you picked, with the day only. A wish is kept without your wallet.
• Error reports: when a page breaks in your browser, what went wrong and the page's address, which we keep in our server logs.

We keep most of these with no set end date.

Like any website, our servers see your IP address when you visit. We use it to slow down abuse, for example to limit how many new names come from one network in a day. We do not keep it in our database. The only thing made from it that we keep is the faucet's scrambled code above, with the wallet it sent to.

What stays in your browser

These are kept in your browser. Clearing this site's data in your browser removes them.

• The wallet you picked. When your wallet already lets this site see your address, Yoink connects it again when you come back, without asking you anything. When you choose Disconnect, or Sign out on this page, your browser remembers that, and Yoink waits until you connect again. A published app keeps its own choice, and may connect your wallet again even after you disconnect there.
• Your drafts: the apps you are working on in the builder. Each time you build or change one with the AI, what you ask for and its files are sent to Yoink and our AI provider for that step. Pictures and token or collection details you add are also kept by Yoink, as listed above.
• Your bookmarks: the games you saved for later.
• Payments in progress: the transaction of a payment you sent and what it paid for. If the page closed before Yoink saw it, the builder sends it to Yoink again the next time you open it signed in with that wallet, for up to 7 days.
• Sealed choices: in a game where you seal a choice and reveal it later, your choice and the secret that seals it, until you reveal it. If you clear them first, you cannot reveal that choice.
• Small choices, such as whether a sidebar is folded, and that Yoink already offered you a name.

Why

To sign you in, to run the builder and keep track of your usage, to show profiles and your Following tab, to publish what you build, and to keep the site safe from spam and abuse. We do not sell your data and we do not show ads.

What is public

• Your username, picture and bio are public, and so is when you made your profile. Anyone can see them next to your wallet address.
• How many people follow you, and how many you follow, are public. The list of wallets you follow is shown only to you.
• The games you launch and publish are public, and so is anything you do onchain. The blockchain is public by design, and nobody, Yoink included, can change or remove what is on it.
• A published app's files and description are public. For a Yoink, the description is the story you gave it.
• Anything else you asked the builder for is private. Only you can see it on Yoink, signed in with the wallet that launched the app. The builder may still use your words in the app's files.
• Reports are private. Only Yoink sees them, and the wallet you report is not told who reported it.
• The art of a launched game is public (a collection set to reveal later, once it is revealed), and so are a token's picture, description and links, with their latest 50 changes and the wallet that made each.

Your picture

A picture you upload is never stored as you sent it. We turn it into a small square image first, which removes its hidden details, such as where and with what camera it was taken.

When you replace or remove your picture, the old one is deleted from our storage. A browser that already showed it may keep its own copy for up to a day.

Pictures for tokens and collections

A picture you add for a token or collection is kept at its full size, but never exactly as you sent it. We remove its hidden details first, such as where and with what camera it was taken. A JPEG or WebP picture is saved again as a new file to do this, which can change it very slightly. Until your game launches, only you can see it on Yoink.

Once a game with art launches, its art is public (a collection set to reveal later, once it is revealed). Anyone can see it in the game's app and on its page on Yoink. Yoink can also put a collection's art on IPFS, a public storage network. Anything on IPFS can be copied and kept by anyone, so treat launched art as public for good. Nobody, you or Yoink included, can take it back from every copy.

The picture, description and links of a launched token can be changed by its creator. The token's latest 50 changes are public, with when each was made, the wallet that made it and, for a change after launch, the signature that approved it. The game's page lists them.

Before we keep a picture for a token or collection, we send it to Project Arachnid Shield, run by the Canadian Centre for Child Protection, which checks it against known child sexual abuse material. A picture that matches is refused and kept apart for legal reasons, and the wallet that added it can no longer add pictures for tokens or collections.

When you report a picture, we keep the reason, and your note and contact details as listed above, so we can answer you. If a picture breaks Yoink's rules, we stop showing it and remove the copies we put on IPFS. We may keep a private copy when the law asks us to.

Who helps us run Yoink

Our database and files are kept by our hosting providers (Railway and Cloudflare). When you build with the AI, what you ask for, a small copy of a picture you add to your idea and your app's files are sent to our AI provider (Anthropic) to do the work. Yoink puts art on IPFS through our storage provider (Filebase). When you connect a wallet app with WalletConnect, the connection goes through Reown.

The builder's preview runs your app in a frame from CodeSandbox, which sees your IP address. An app built with the AI loads styles from Tailwind's CDN, and fonts from Google when its look uses them, and a published app can reach other sites its creator chose. Those sites see the IP address of anyone who opens the app.

To read the blockchain, our servers and sometimes your browser ask a network provider. It sees which addresses are read, such as your wallet's, and your IP address when your browser asks.

Connecting a wallet app with WalletConnect

You can connect a wallet app on your phone with WalletConnect, a service run by Reown. When you pick WalletConnect, the connection goes through Reown's relay, and Reown's Verify service checks the page you are on. Both see your IP address and the address of that page.

Reown's connect window also tells Reown when it starts and when you connect, with the page address and, once you are connected, your wallet address. It starts again each time a page reconnects you with WalletConnect. What Reown does with this is covered by Reown's own privacy policy.

A wallet in your browser, such as an extension, never goes through Reown. Nothing goes to Reown until you pick WalletConnect. Once you do, Reown's software keeps the connection in your browser, so a page can reconnect you.

Asking for removal

You can clear your bio and remove your picture yourself at any time, unless Yoink has hidden your profile. A removed picture is deleted. To ask us to remove your whole profile, or for a copy of what we hold about your wallet, write to privacy@yoink.markets. Tell us your wallet address. We may ask you to sign a message with that wallet, to be sure the request is yours.

A username is permanent, so it cannot be changed. When we remove a profile, we delete its picture and its bio and hide its name. The name then shows nowhere and your wallet shows as a plain address, with its games. We keep the name itself, so nobody else can take it and pass for you.

Hiding is not deleting. When we hide a profile for breaking the rules, its name, picture and bio stop showing on every public page and its picture is deleted, but its name and bio stay in our records, and the name stays taken. If a name was taken to pass for someone else, such as a brand, a project or a creator, we can free it so the real one can use it. What is onchain cannot be removed by anyone.

Anything we delete from our database can still be in its backups.
