Questions
Do you ever see my logins or bank data?
No, and it is worth being specific rather than just promising. Stackyard reads two things: the offer tiles on your issuer's offers page, and the deal listings on your buying group. It has no code that touches password fields, login forms, balances or statements. You can check that yourself: the source is open, whether you install it from the Chrome Web Store or load it unpacked from the code directly.
The bigger point: there is no server. Nothing was ever built to receive your data, so there is nowhere for it to go. Open your network tab and watch. The only outbound request Stackyard ever makes is to a Discord webhook you create yourself, and only if you turn alerts on.
How do I get it?
It's free on the Chrome Web Store. Install it and you're in, no waiting.
Which cards does it support?
The major issuers, with more added as we validate them. Coverage varies by card, since how often an offer stacks depends on whether your issuer's offers actually overlap with what the buying groups sell that week.
Which browsers does it work in?
Chrome, plus Chromium browsers like Edge and Brave.
What happens to my data if I uninstall it?
It goes with it. Everything lives in your browser's own storage, so there is nothing on our side to delete.
