Privacy
Last updated June 10, 2026
This is the short version of how Stacks handles your data, written to be read. The principle behind all of it: your collection is yours, and we’re not in the data business.
What we collect
- Account basics — your email address, username, and display name.
- Your content — the cards and stacks you save: notes, images, links, files, and their metadata.
- Operational data — standard server logs and the minimum technical information needed to keep the service running and abuse-free.
We don’t run advertising trackers, we don’t profile you, and we don’t sell or rent your data to anyone.
Where it lives
Your data is stored with Supabase in the European Union (Frankfurt) and served through Vercel. Files you upload are stored in the same region.
Cookies
Stacks uses cookies only to keep you signed in and to remember interface preferences — like which view you last used. No third-party advertising or analytics cookies.
Third parties
We use a small set of processors to run the service: Supabase (database, authentication, storage), Vercel (hosting), and — when paid plans launch — Stripe for payments. Payment details go to Stripe directly and never touch our servers.
Visibility of your content
Everything you save is private by default. Content becomes visible to others only when you make a stack public or unlisted, share a link, or invite collaborators — and you can reverse any of those at any time.
Your rights
You can access, correct, or delete your data at any time — through the product where possible, or by emailing hello@stacks.plus. Deleting your account removes your content from the service.
Changes
If this policy changes in a way that matters, we’ll say so on this page with a new date — not bury it.
