Delete my data
Here you ask us to delete the personal data Dados B3 holds about you. To prove the e-mail is yours, we send a single-use link to it. Nothing is deleted without that proof.
What we keep, why and for how long
- Free key and subscription (at Stripe): e-mail, key and plan status. To deliver the key and the plan. While the customer record exists at Stripe.
- Notices you asked for (follow a company, weekly bulletin, Saturday magazine, Monday portfolio): e-mail and, for the portfolio, tickers and quantities. To send the notice. While active; deleted 365 days after you leave. Company alerts, the bulletin and the magazine start right away; an old request (before 30/10/2026) or a portfolio request not confirmed in 7 days is deleted.
- Business plan trial request: name, work e-mail, company, intended use and, if you gave it, the CNPJ. To answer the request. Deleted 365 days after it was made.
- Usage counts: only a hash of the key, per day. To apply the daily limit. Deleted after 365 days.
- "Do not send" list: only a hash of the e-mail. So we do not write again to whoever asked to stop. Kept for good.
- Daily backup: a copy of the files above on the same disk, kept 7 days.
How to delete
- Type below the e-mail you used on Dados B3.
- Open the link we send to that e-mail.
- Read what will be deleted and click the button.
What is deleted and what stays
Deleted: your customer record at Stripe (name, e-mail, phone and key are emptied, then the record is deleted); the notices you asked for, with the e-mail and the portfolio; the weekly-send history; the Business plan trial request; waiting e-mails addressed to you; the usage and refusal counts linked to your key.
Stays, and why:
- Charges and invoices that Stripe keeps because tax and accounting law require it. We cannot delete them. We delete the customer record that points to them.
- A hash (not the e-mail) on the "do not send" list, so no campaign or reminder is sent to this address again.
- The record of this deletion request: a hash of the e-mail, the date and how many items were deleted. It proves we answered you.
- The campaign log, with the e-mail replaced by its hash.
- The daily backup, which drops these data by itself within 7 days.
- The technical logs of our host (Render), which we do not control.
Warning: if you have an active subscription, deleting the record cancels it and the key stops working. We do not refund automatically; write to the contact below if you need that.
