The key is stored encrypted with AES-256 on servers in the European Union and never goes back to your browser. Disconnect whenever you like and it is deleted. Where Trading 212 lets us see the permissions, we check that the key cannot trade or withdraw and, if it can, we reject it.
Frequently asked questions
Can Celsmar trade in my Trading 212 account?
No. Celsmar only reads your holdings with a read-only key and never sends orders or moves money. If Trading 212 shows the key's permissions and it can trade or withdraw, we reject it.
How often does my Trading 212 portfolio update?
Every night, automatically, and whenever you press Sync in the portfolio (at most once a minute). Whatever you buy or sell at the broker is recorded on its own.

Connecting brokers is part of the Pro plan, with up to five brokers at a time; on Enterprise, as many as you like. On Free you can see the brokers and how they connect.
What if I would rather not create a key at Trading 212?
You can import your Trading 212 statement as CSV or Excel: the portfolio recognises it and nets buys and sells into your holding with its average price. A screenshot works too.
