Privacy Policy

Last updated: October 16, 2026

What we collect

Payment details are handled by Polar, our merchant of record, and never touch our servers.

How we use it

To operate the Service for you, and — only if you opt in — to send you marketing emails (see below). We do not sell or rent your personal data. We share it only with the processors below, and in a business transfer as described below.

Emails

Account emails (such as confirmation links, password resets, setup help, and billing receipts) are sent as needed to run the Service. Marketing emails — product updates, tips, and offers we think you'll find useful, including partner offers — are sent only if you opt in. We record when you opted in and the wording you saw. You can withdraw at any time with the unsubscribe link in every marketing email or by emailing us. We never give your address to partners; if you buy something we recommend, we may earn a commission.

Processors

Supabase (database & authentication), Polar (payments, as merchant of record), Vercel (hosting), and email service providers (to send account and marketing emails). Each stores only what is needed for their function.

Data isolation

Your data is stored per-account and protected with row-level security — no other user can read it. Add-on uploads are authenticated with a per-account API key that you can revoke at any time.

Deletion

Deleting an account in the app removes its trades. Contact us to delete your entire user account and all associated data.

Where your data is stored

Our database (Supabase) and hosting (Vercel) run in the United States, and our email provider (Resend) is a US company. For personal data transferred from the EEA or the UK to the United States, we rely on the European Commission's Standard Contractual Clauses and the UK Addendum in these providers' data processing terms.

How long we keep it

Your email, trades and settings are kept while your account exists. When your user account is deleted, they are removed from our database. Copies can remain for a while in backups, which we keep only to recover from mistakes and never use for anything else.

If you are in the EEA or the UK

We use your data to provide the Service you signed up for (your account, syncing and analysing your trades, support and your plan status); for our legitimate interests in keeping the Service secure and in measuring which links and ads bring visitors and how our pages are used; and, for marketing emails, with your consent. We don't make decisions about you based solely on automated processing.

You have the right to get a copy of your personal data, to have it corrected or deleted, to restrict or object to how we use it, and to receive it in a portable format (you can export your trades to CSV in the app at any time). Where we rely on your consent, you can withdraw it at any time. Email us to use any of these rights and we'll reply within one month. You can also complain to the data protection authority where you live or work; in the UK this is the Information Commissioner's Office (ICO).

Business transfers

If we sell or transfer the Service or its assets, or are part of a merger or reorganization, personal data we hold — including email addresses and email preferences — may be among the transferred assets. We'll let you know by email or on the site if this happens.

Changes to this policy

We may update this policy from time to time by posting a new version on this page. Material changes will be announced on the site.
