Privacy
Last updated 8 August 2026
Short version: the calculator needs no account, sets no advertising cookies, and runs no analytics or trackers of any kind. The numbers you type stay in your browser.
What stays on your device
Your balance, your risk percentage and your minimum reward-to-risk are saved in
your browser's local storage (rapater.rules.v1), as is anything you
log (rapater.journal.v1). These are not sent to us. Clearing your
browser data removes them.
What is sent to our server
- The signal text you paste, when you press the button. It is sent to our parse endpoint so the symbol, direction, entry, targets and stop can be read out of it.
- Your IP address, which Cloudflare provides with every request. It is used to count requests per hour so the endpoint cannot be run up as a bill, and for that purpose it is discarded within 48 hours.
- Your IP address, kept for seven years, in one case only: when you accept the Terms of Service and Refund Policy. Accepting is a signature (§20.11), and the record of it holds the time, your account, your IP address and a cryptographic hash of the exact text you were shown — so that what you agreed to can be proved later, and so a subsequent amendment can never be mistaken for it. Nothing else keeps an IP address beyond 48 hours.
Who else sees the signal text
The signal text is sent to Anthropic's API to be read. We use their Claude Haiku model for that and nothing else. Do not paste anything into the box that you would not want sent to a third-party service — it is a trading signal box, and it should only ever contain a trading signal.
If that request fails, a much simpler pattern-matcher runs inside your own browser instead, and in that case the text does not leave your device at all.
If you connect Telegram
Telegram forwarding is not built yet — there is no bot and nothing to connect today. This describes what will happen when it exists, so it is written down before it is switched on rather than after.
Forwarding a signal to the bot sends that message's text to Anthropic's API to be read, exactly as pasting it into the calculator does. Your Telegram user id is stored so the reply goes back to you and so the verdict is sized against your own rules; it is the only thing that links a Telegram chat to a Rapater account. Connecting is done entirely inside Telegram — there is no field on this website where you would ever type a credential, and there never will be.
You can disconnect at any time by writing to info@lavoosh.com, which deletes the link between your Telegram account and your Rapater account.
If you sign in
Sign-in is by one-time link. We store your email address and, for each session, a hashed token — never a password, because there is no password. Email is sent through Postmark. Anything you save to a journal is stored against your account in Cloudflare D1.
What we never collect
No advertising or analytics cookies. No tracking pixels. No third-party scripts of any kind — you can check the page source. No exchange API keys, no wallet addresses, no payment details, and no access to any account you hold anywhere.
Where it is stored
On Cloudflare's platform (Pages, D1 and Durable Objects). Rate-limit counters expire within 48 hours. Terms acceptance records are kept for seven years, which is the one thing here with a long retention and the reason is that it is a signature.
Deleting it
Local data: clear your browser storage. Anything held against an account: write to info@lavoosh.com and it is deleted, including the account itself.
