Visiting. Our hosting provider (Cloudflare) processes standard request data such as IP address and browser type to deliver pages and stop abuse. We keep aggregate counts only: page views per page, referring site and country. Daily visitor totals are counted with a one-way hash whose secret is discarded every day, so the counts cannot be traced back to a person. We do not build visitor profiles.
Membership. When you start a payment we store the invoice (plan, amount, time). When it is paid we store the transaction ID and the access key with its expiry date. We do not ask for your name or email.
Your device. The access key and your lab settings are kept in your browser's local storage so you stay unlocked. You can remove the key on the Pro page.
Blockchains are public. A payment you send is visible on-chain to anyone, as with any crypto transfer.
AI assistants (MCP connector and JSON API). When an assistant such as Claude or ChatGPT asks Provyan for a study, we receive only the request itself: a coin, a signal and filters. We do not receive your conversation, your name or your account. The connector is read-only, needs no sign-in, returns the same public statistics shown on this site, and we keep only a daily count of how often each tool was used. Details are on the assistants page.
