How these tools work

Local by design
Your data stays yours. Everything runs in your browser — there is no server to upload to, so there's nothing for us to see, store, or leak.
Free first
Every tool does its job free, no account needed. Paid tiers only exist where heavy use begins — and they're one-time, not subscriptions.
Request-driven
Shaped by the people using them. Each tool has a feature-request link; the most-asked-for thing gets built next.
