Cookie and Storage Notice
Manna sets only sign-in cookies (one to keep you signed in, one briefly while you sign in with Telegram) and uses no analytics, advertising or tracking cookies. This notice lists everything Manna stores on your device and why.
This notice explains what Manna ("Manna", "we", "us") stores in your browser or app, and why. It is part of our Privacy Policy.
The short version: Manna sets one cookie that keeps you signed in, plus a short-lived one while you sign in with Telegram. We do not use analytics, advertising or tracking SDKs, and we set no third-party analytics or advertising cookies. Everything else we store on your device remembers your preferences or makes features work, and stays on your device.
1. What cookies and local storage are#
A cookie is a small file a website stores in your browser and sends back to the site with each request. Local storage and session storage are similar browser features that let a site keep small pieces of data on your device. Session storage is cleared when you close the tab; local storage stays until you or the site clear it. The Manna apps use equivalent storage on your device.
2. Manna's cookies#
| Name | Purpose | Type | Duration |
|---|---|---|---|
manna_session | Keeps you signed in. It holds your wallet address, chain and expiry (and, after a Telegram sign-in, a random session id so you can revoke it), signed by our server so it cannot be forged. | Strictly necessary, first-party | 30 days, or until you sign out |
manna_tg_login | Only while you sign in with Telegram: a random secret that proves the sign-in is collected by the same browser that started it. Sent only to Manna's Telegram sign-in endpoint. | Strictly necessary, first-party | 30 minutes, removed once you are signed in |
The cookies are httpOnly (scripts on the page cannot read them), Secure (sent only over encrypted connections in production), and SameSite (Lax for manna_session, Strict for manna_tg_login: not sent with cross-site requests, which helps prevent cross-site request forgery). They are not used to track you across other websites.
3. Local and session storage used by Manna#
We do not use these items to track you, and the preference items never leave your device, except where noted below.
Strictly necessary (features work without asking you every time)#
| Key | Storage | What it does |
|---|---|---|
manna.me | Local | Remembers the signed-in wallet address and avatar, so the app shows your account straight away |
manna.solConfig | Session | Reuses a prepared Solana launch configuration for up to 30 minutes if you retry a launch with the same settings |
manna.nav | Session | Remembers the pages you visited in this tab, so the back button works |
manna:reload:<page> | Session | Stops the app reloading a crashed page in a loop |
Preferences#
| Key | Storage | What it does |
|---|---|---|
manna.feedPrefs | Local | Your feed filters and settings |
manna.panels | Local | Which panels are open or collapsed |
manna.callersPeriod, manna.holdersPeriod, manna.trendingPeriod | Local | The time period you picked on leaderboards and trending lists |
manna.watch | Local | Coins you starred on this device while signed out |
manna.watch.merged:<wallet> | Local | Notes that this device's starred coins have been added to your account's watchlist |
manna.quick.<QUOTE> | Local | Your quick-buy amount for each pair asset (for example, SOL) |
manna.quickusd | Local | Your quick-buy amount in US dollars |
manna.chart | Local | Whether charts show as a line or candles |
manna.marks | Local | Whether trade markers show on charts |
manna.chain | Local | The chain filter you last picked on the home list |
manna.view | Local | Your list or grid view choice |
manna.portfolio.prefs | Local | Your portfolio sort order, chain filter and whether to hide dust |
Referral attribution#
| Key | Storage | What it does |
|---|---|---|
manna.invite | Local | The invite code from a link you opened, so the person who invited you is credited when you sign up |
manna.tradeRef | Local | A referral code from a trading link, credited on your trades (and used as your invite if you have no other) |
manna.ref.<coinId> | Local | A referral code from a link to a specific coin, credited on trades of that coin |
Referral codes are sent to our servers when you sign up or trade, so the referrer can be credited as described in the Fee Schedule.
4. Storage set by sign-in and wallet libraries#
Manna uses third-party libraries that store their own items on your device so sign-in and wallet connection work:
| Provider | Purpose |
|---|---|
| Privy | Sign-in, session with Privy, and your embedded wallets |
| wagmi | Remembering which EVM wallet you connected |
| Solana wallet adapter | Remembering which Solana wallet you connected |
These items are strictly necessary for the features you use. Privy also runs some of its features in its own window on its own domain (for example, exporting your keys), where Privy's own cookies and storage apply under Privy's privacy policy. When you open a third-party site from Manna (such as a block explorer or DexScreener), that site's own cookies apply.
5. What we do not use#
- No analytics cookies or analytics SDKs.
- No advertising cookies, pixels or ad SDKs.
- No cross-site tracking or fingerprinting.
- No sale or sharing of storage data with advertisers.
Because we only use strictly necessary storage and preference storage that stays on your device, we do not show a cookie consent banner. If we ever add optional cookies, we will ask for your consent first where the law requires it, and update this notice.
6. Your choices#
- Sign out to remove the
manna_sessioncookie. - Clear site data in your browser settings to remove the cookie and all local and session storage for mannas.fun. You will be signed out and your device preferences will reset. Data saved to your account (such as your profile) is not affected.
- Block cookies in your browser. If you block the
manna_sessioncookie, you will not be able to stay signed in.
7. Changes#
We may update this notice when what we store changes. The "updated" date at the top shows when it last changed.
