This policy explains what data MonoStack (“we”, “us”) handles when you use our website, the free browser tools (Sweep Scanner, Trap Meter, Sweep Autopsy) and the SweepCheck app. We keep it simple: we build market tooling, not an ad business.
01What we collect
- Market data you request. When you open a coin, the app fetches public market data (liquidations, open interest, funding, candles) from exchange APIs. This is price data — not personal data.
- Account / subscription data. If you subscribe to SweepCheck we store the email associated with your account. Payments are processed by a merchant of record; we never see or store your full card number.
- Newsletter email. If you subscribe to the daily report, we store your email to send it and to let you unsubscribe.
- Diagnostics. Basic, aggregated error and usage signals used to keep the apps working. We don’t sell this.
02The browser apps & permissions
- activeTab — to read the chart / coin on the tab you click.
- storage — to remember your on/off preference per site.
- Read-only market data — requests to public endpoints of Bybit, Binance and OKX.
We do not collect your browsing history, read exchange account data, access other tabs, or load remote code. Any alerts (e.g. Telegram) only fire for the coins you choose to watch, and only after you connect them.
03Cookies & analytics
Our website uses only what’s needed to serve pages (hosting and basic traffic stats, typically via our hosting provider Cloudflare). We don’t use invasive cross-site advertising trackers.
04Sharing
We share data only with the providers needed to run the product: our hosting/CDN, our payment merchant of record, and our email provider (for the newsletter). We do not sell your personal data.
05Retention
Newsletter emails are kept until you unsubscribe. Account data is kept while your subscription is active and for a short period afterwards for billing/legal reasons. Aggregated market history (which contains no personal data) may be retained indefinitely to power the product.
06Your rights
Depending on where you live, you may have the right to access, correct, export or delete your personal data, and to object to certain processing. To exercise any of these, contact us below.
07Children
Our products are not directed to anyone under 18 and we do not knowingly collect their data.
08Changes
We may update this policy as features launch. Material changes will be reflected by the “last updated” date above.
