Privacy policy

Last updated 7 October 2026

Firstprint is a free prediction game about crypto token prices, played with points that have no cash value. This page explains what we collect, why, and how to have it removed. We don’t sell your data, show ads, or use tracking or advertising cookies.

What we collect

When you sign in with Google: your email address and name. We use the name only to suggest a username. We never see your Google password.
When you sign in with an email code: your email address, so we can send you the code and recognise your account.
When you sign in with a Solana wallet: your wallet’s public address. Signing in only signs a message. It never sends a transaction or touches your funds.
Your activity: your username, points balance, daily streak, predictions and point history, so the game works and the leaderboard is accurate. Your username and predictions are shown publicly on market pages, the leaderboard and your public profile page, which also shows your win rate and points won. Your email address, wallet and X username are never shown there.
Your X username, if you link it: so tasks on X can be credited to you. To check a task we look only at public information on X: your bio or recent posts (for your verification code), and whether you followed, reposted or posted. We never log in to X or post for you. One X account can be linked to one Firstprint account.
Your Telegram user ID, if you link it: when you press Start in our bot for the “join our channel” task, we keep your Telegram user ID to check that you joined. We don’t read your messages or contacts. One Telegram account can be linked to one Firstprint account.
Invites: if you sign up through a friend’s invite link, we record who invited you so they can get their reward.
TestFPT claims: when you claim, we record the wallet you claimed to and the transaction. Transactions on Solana’s public test network, including your wallet address and the TestFPT you receive, are visible to anyone on that network.
Your Firstprint wallet: if you sign in with Google or an email code and have no wallet linked, we create a Solana wallet on the public test network for you. We keep its key encrypted, with the decryption key stored separately from our database, and use it only for Firstprint. Your daily streak, rewards, predictions (stakes, winnings and refunds) are recorded with it as TestFPT movements, and those transactions (with the wallet address) are visible to anyone on that network.
A sign-in cookie: one cookie (fp_session) that keeps you logged in for up to 30 days. We store only a scrambled (hashed) copy of it.
Your IP address: used briefly to stop abuse, such as too many sign-in attempts. It is kept in memory and not stored with your account.
Your country: the country Cloudflare reports for your connection when you first sign in, stored with your account so we can see where players come from in totals (for example, “40 players from India”). We don’t store your IP address or anything more precise.

The practice version

The practice market on the home page keeps everything in your own browser’s storage. Nothing from it is sent to us.

Who helps us run Firstprint

These companies process data for us only to provide their service:

Render hosts this website, the app and its database.
Cloudflare sits in front of our domain to keep it fast and protect it from attacks. It sees your IP address and the pages you request.
Supabase stores private backup copies of the database.
Google provides “Continue with Google” sign-in, and serves the fonts on our pages (your browser requests them from Google, which sees your IP address).
Resend sends sign-in codes and, if you signed in with email, a short email when a market you played settles.
Vercel may host a copy of this website.

Market data comes from the exchanges and price sources named on each market, for example MEXC’s public list of trading pairs and prices, and CoinGecko for trending tokens. Logos an admin adds are downloaded and stored by us. No personal data is sent to these sources.

We post new markets, reminders and results to our public Telegram channel. These posts contain no player data. If you join the channel or open it from the app, that is between you and Telegram, under Telegram’s own privacy policy. For the “join our channel” task, our bot checks only whether your linked Telegram account is a member of the channel.

Statistics we share

We may share totals with partners, such as the number of players, predictions and points staked. These are counts and sums only: they never include names, usernames, email addresses or wallets.

How long we keep it

We keep your account and activity while your account exists. Sign-in codes expire after 10 minutes and are deleted. We also keep private backup copies of the database: a latest copy refreshed every few minutes, and daily copies kept for 30 days. If you delete your account, older backups may still contain your data until those copies are deleted.

Your choices

You can ask us to see, correct or delete your account and its data at any time by emailing [email protected] from the address you signed in with, or by telling us your wallet address. We’ll reply within 30 days. Deleting your account removes your email, wallet link and points.

Age

Firstprint is not meant for anyone under 18.

Changes

If we change this policy, we’ll update this page and the date at the top. For anything that significantly affects how we use your data, we’ll also tell you in the app.
