Privacy
Jelly Charts is a trading replay, journalling and backtesting tool run by one person. This page says plainly what it stores and why. It is not a legal document written to sound impressive; if something here is unclear, email and ask.
What is stored
- Your email address. It is the only account identifier. It is used to email you a sign-in link and to match your Stripe subscription to your account.
- Your journal and your strategies. Trades, notes, tags, settings and any Python an AI agent wrote for you live in a database created for your account alone, hosted on Turso. No other account can read it.
- Market data you upload. The 1-minute bar files you upload are stored so the app can replay them back to you. Jelly Charts does not sell or redistribute market data and does not include any.
- A sign-in cookie. One cookie,
jelly_session, set for 30 days. It is HTTP-only and HTTPS-only and holds nothing but your signed email address.
Payment
Payment is handled by Stripe. Card details are entered on Stripe's own checkout page and are never sent to, seen by, or stored by Jelly Charts. Jelly Charts receives only your email address and whether the subscription is active. Stripe's own privacy notice applies to what it holds: stripe.com/privacy.
Sign-in links are sent through AgentMail. At present they are sent from an address on
askelira.com, another site run by the same person; that is why the sender
domain does not match this one.
The AI agent
If you use the AI agent, you supply your own OpenRouter API key and your prompts go to OpenRouter under your key. Do not paste anything into it you would not want to leave this machine.
What is not done
There is no advertising, no analytics or tracking script, no third-party pixel, and your journal is never sold, shared or used to train anything.
Deleting your data
Email alvin.kerremans@gmail.com and ask. Your database, your uploads and your email address are deleted. Stripe keeps its own payment records for as long as its own rules require.
Not advice
Jelly Charts is a practice, journalling and research tool. Nothing in it is financial advice. Trading futures involves substantial risk of loss, and simulated or backtested results do not guarantee future results.
