Your data, your machine.

The idea

Most sites store your data on their servers and hand you a login. The Local Standard inverts that: your profile lives in your browser's local storage, under your control. We deliver static pages; the only thing that runs on our edge is an anonymous tool-use counter. There is no server-side database of who you are or what you like - because we never receive it.

What's stored, and where

One key in your browser's localStorage, named cosmodev:profile. It holds:

• Identity - an optional display name and an avatar color. No email, no password, no identifier.
• Favorites - the tools you've starred (★).
• Preferences - theme, code font, syntax color scheme, reduced-motion.
• Stats & recents - optional, per-tool local counts and recent values.

Inspect it yourself: open your browser devtools → Application → Local Storage → this site. It's a plain JSON object. You can read it, edit it, or delete it.

What we actually collect

One thing only: an anonymous, running count of how many times each tool is used(the “12 uses” number under the reactions). That count is global - it is not tied to you, your profile, your browser, or any identifier. We cannot and do not link it back to anyone.

• ✓ No accounts, no logins, no emails.
• ✓ No cross-site tracking, no analytics fingerprinting.
• ✓ Your favorites, name, and settings never leave your device.

Portability

From your account menu → Data, you can Export a single.json file containing your whole profile, and Import it on any other browser or machine. On import you choose:

• Merge favorites - adds the backup's stars to your current ones.
• Replace all - overwrites your current profile with the backup (confirmed).

Security - honestly

Two layers, and it's worth being precise about what each protects:

• The export file. Every export carries a SHA-256 checksum(tamper/corruption detection, always on). Add a passphrase and the contents are encrypted withAES-GCM-256, keyed by PBKDF2-SHA256 at 600,000 iterationsfrom your passphrase. This protects a backup at rest - e.g. a laptop theft or a cloud-sync folder. The key never leaves your head; carry the passphrase to the new machine to restore.
• The live profile. By default, your profile inlocalStorage isplaintext by design. That's the point: it's yours, on your machine, inspectable and editable. If you share the device, Settings offers opt-in at-rest encryption: it guards the stored profile against other users of this device and local malware — but a forgotten passphrase cannot be recovered, and no in-browser lock protects against someone who controls the device while it's unlocked. Treat your browser profile like you treat any local file - lock your device.

Delete it

Account menu → Data → Clear profile, or your browser's “clear site data.” Either way it's gone for good - there's no server copy to delete because there was never a server copy.
