Privacy Policy
Effective 17 September 2026
This policy explains what Zentiment collects, why, who it is shared with, and how long it is kept. It applies to zentiment.ai, its browser notifications, and the Zentiment Telegram bot.
What we collect
- Account identity. When you sign in with email, Google or X, our authentication provider gives us a stable account identifier and, where available, your email address. We never receive your password, and we never ask for a wallet.
- What you ask us to watch. The wallet addresses you add, the names and notes you give the traders you group them under, and which networks you selected. Names and notes are free text you write — they are private to your account, and we recommend not putting anything sensitive in them.
- Telegram binding. If you connect Telegram we store your numeric chat identifier and, if your account has one, your Telegram username.
- Browser notification subscriptions. If you turn on browser notifications we store, for each device, the push endpoint your browser was issued, the two public keys your browser generated so we can encrypt to it, and a shortened description of the browser itself so you can tell your devices apart in settings.
- Blockchain activity. Public on-chain transactions involving the addresses you monitor, and our structured interpretation of them.
- Operational records. Delivery status of alerts, and server logs needed to run and secure the Service.
- How you use the Service. Which pages you open, which buttons you press, and your browser, language, approximate location from your IP address, and referring link. This is tied to the account identifier above and to nothing else — not your email, not a wallet address, not a name you wrote. We collect it to see which parts of the product are used and which are confusing, and for no other purpose. If your browser sends a Do Not Track signal we collect none of it.
What we do not collect
We do not collect private keys, seed phrases or signatures — the Service has no ability to use them and never asks. We run no advertising, no advertising or marketing trackers, and nothing that follows you to any other site: the usage data described above is first-party, is never combined with data from elsewhere, and is never sold, shared or used to build a profile of you outside this Service.
Why we process it
To provide the Service you asked for: to know which addresses to watch, to record what they did, to deliver your alerts, and to keep the Service secure and working. This is processing necessary to perform our contract with you, and our legitimate interest in operating a secure service.
Who it is shared with
We use the following sub-processors, and share only what each one needs:
- Privy — authentication. Receives your sign-in identity.
- Chainstack — EVM blockchain data. Receives the wallet addresses you monitor as part of ordinary blockchain queries.
- Helius — Solana blockchain data. Receives the Solana addresses you monitor, so it can notify us when they transact.
- Telegram — alert delivery. Receives the content of each alert: the trader name you wrote, the wallet address, the network, and the assets and amounts that moved. Telegram messages are not end-to-end encrypted by default.
- Your browser's push service — Google, Apple or Mozilla, depending on the browser — browser notification delivery. Every notification is encrypted for your device before it leaves us, so the push service can see that a message was delivered to your browser and when, and not what it says.
- DigitalOcean — hosting and database.
- PostHog — product analytics. Receives the usage data described above, identified by your account identifier and nothing else — no email address, no wallet address, and none of the names or notes you wrote.
We do not sell personal data. We disclose data to authorities only where legally compelled.
How long we keep it
- Account, traders, wallets and subscriptions: until you delete them or close your account.
- Normalised transaction history and alert delivery records: retained while your account exists.
- Raw provider payloads: automatically deleted after 30 days. They exist only so a parsing error can be corrected against the original data.
- Usage data held by our analytics provider: one year.
Your choices
- Remove a wallet or a trader at any time; monitoring for it stops.
- Turn on Do Not Track in your browser and no usage data is collected at all. Nothing else about the Service changes.
- Disconnect Telegram in settings, or send
/stopto the bot. Delivery ends immediately either way. - Turn browser notifications off in settings, for one device or for all of them; the stored subscription is deleted with it. Revoking notification permission in your browser also ends delivery, and we drop the subscription the next time one is refused.
- Delete your account to remove your traders, wallets and subscriptions. Request access, correction, export or erasure at [email protected].
A note on blockchain data
On-chain activity is public and permanent. Deleting your Zentiment account removes what we hold about your use of the Service; it cannot remove anything from a blockchain, and does not affect what our data providers independently hold.
