Your bank statement stays on your device

Stack Scan reads statements with code that runs in your browser. The file, its transactions and your amounts are never uploaded to us or anyone else. What the scan finds (the list of tools, their costs and your choices) is saved in your browser’s local storage so you can come back to your plan. “Start over” deletes it, and so does clearing your browser data.

To show amounts in your currency, the page fetches public exchange rates from frankfurter.dev. That request contains no personal data.

What we do collect

• Forms you choose to send (waitlists, blueprint requests, renewal reminders): your email, and what you type in the form. The renewal-reminder form also sends two totals (number of tools and monthly spend), never your tool list or statement.
• Instant AI verdicts: the tool name you type is sent to our server and to Anthropic, which runs the research model. To cap usage, we keep a one-way hash of your IP address for one day. Results are cached and shown to anyone who asks about the same tool, without any link to you.
• Visit statistics, only if we turn on cookie-free analytics.

Who processes it

Netlify hosts the site and stores form submissions and cached AI verdicts. Anthropic processes AI verdict requests. If a paid plan launches, the payment provider will handle card details; we will never see them.

What we don’t do

We don’t sell your data, share it for advertising, or use cookies to track you across sites.

Your choices

Ask us to see or delete anything we hold about you at @BuildictHQ on X, and we’ll do it within 30 days. Every email we send has an unsubscribe link.
