Privacy Policy

Last updated: 2 August 2026

Quantum ("we") is an analytics terminal for crypto futures at quan.trading. This page explains, in plain terms, what we store about you, why we store it, and how to get rid of it. If something here is unclear, ask before you sign up rather than after.

The short version: we store the minimum needed to run an account and a shared trade feed. We do not sell your data, we do not run advertising trackers, and we never take custody of your funds. Your exchange API keys are the most sensitive thing we touch — section 3 explains exactly what happens to them.

1. Who is responsible

The operator of Quantum is the data controller for everything described here. For any privacy question, correction or deletion request, contact us through the Telegram channel linked in the app or by email at privacy@quan.trading.

2. What we collect and why

Data	Why	Source
Telegram ID and username, or Google account ID and email address	To create and identify your account. This is the only way to sign in — we do not store passwords at all.	You, via Telegram or Google sign-in
Nickname, avatar seed, rating	Shown next to your posts in the community feed and chat.	You / generated
IP address of your most recent request, and a count of the separate days you have visited	Abuse prevention, and an aggregate "active users" figure on the landing page. We keep the latest IP only, not a history.	Automatic
Trade ideas you publish, comments, votes, chat messages, journal entries	These are the product. Published ideas and chat messages are visible to other users by design.	You
Browser fingerprint and IP at trial signup	To stop one person claiming the free trial repeatedly.	Automatic
Payment records (amount, status, provider reference)	Accounting and support. Card and crypto details are handled by the payment provider — they never reach our servers.	Payment provider
Binance API key and secret, if you choose to enable trading	See section 3.	You

We do not use advertising cookies, third-party analytics or cross-site trackers. The only browser storage we use is what the app itself needs: your session token, your interface settings, and your saved chart drawings.

3. Exchange API keys

Trading features are optional. If you do not enable them, we never see an API key.

Keys you enter for the in-browser terminal are stored only in your own browser (localStorage) and are sent directly to Binance. They are never transmitted to us.
If you switch on server-side auto-trading, the key must live on our server to place orders while your browser is closed. It is encrypted at rest with AES-256-GCM and is never written to logs or returned by any API.
We strongly recommend creating a key with trading enabled and withdrawals disabled, restricted to your own IP where possible. We cannot move funds off your exchange account and never ask you to enable withdrawal permissions.
You can remove a stored key at any time from the app; deletion is immediate.

4. Legal basis

Where the GDPR applies, we rely on: contract for account data and anything needed to deliver the service; legitimate interest for abuse prevention and aggregate usage counts; and legal obligation for payment records. Where consent is the basis, you may withdraw it at any time.

5. Who else sees your data

We share data only with the providers required to operate the service:

Telegram and Google — sign-in only.
Binance — market data and, if you enable it, your own orders.
Payment providers — to process a payment you initiate.
Hosting and database providers — infrastructure we run on.

We do not sell personal data and we do not share it for advertising. We may disclose data if legally compelled to.

6. How long we keep it

Account data — while your account exists, then deleted within 30 days of a deletion request.
Published ideas, comments and chat messages — retained as part of the public record; on request we detach your name from them.
Payment records — as long as accounting rules require.
Anti-abuse fingerprints — up to 12 months.
API keys — until you remove them or delete your account.

7. Your rights

You can ask for a copy of your data, correct it, have it deleted, restrict or object to processing, and receive it in a portable format. Write to privacy@quan.trading and we will respond within 30 days. If you are in the EU or UK you may also complain to your national data protection authority.

8. Security

Traffic is encrypted in transit (TLS). Secrets are encrypted at rest. Access to production data is limited to the operator. No system is perfectly secure: use a withdrawal-disabled API key, and tell us immediately if you suspect your account has been compromised.

9. Children

Quantum is not intended for anyone under 18 and we do not knowingly collect their data.

10. Changes

If we change this policy in a way that materially affects you, we will say so in the app before the change takes effect. The date at the top always reflects the current version.

Not financial advice. Quantum is an analytics tool, not an investment advisor. Crypto futures trading carries a high risk of losing your entire deposit. Figures shown in the product are simulations and past results, and are not a promise of future returns.
