01

The cloud is just someone else's computer. Keep yours.

Why local-first

Every Tynkr app reads and writes plain files in a folder you choose. Open them in any text editor. Sync them however you like — or don't. When we shut down someday, your software keeps working.

No servers

Nothing leaves your machine

No telemetry, no analytics, no accounts. The only network request any Tynkr app ever makes is an optional check for updates — and you can turn that off. Airplane mode is a supported configuration.

Open formats

Files you can actually read

Your ledger is JSON. Your notes are Markdown. No proprietary database, no export hostage-taking. Grep it, script it, back it up with anything.

No rent

Buy once. Own forever.

One-time purchase per app. No monthly toll, no account to create, no license server to phone home. Software the way it used to work.

02

Four operating systems for your life's back office.

The suite

Each app is a complete, self-contained system. Same design language, same file-first philosophy, same one-time price.

Run a whole business from one app that never bills you monthly. Invoices, CRM, purchase orders, contracts, expenses with receipts, proposals — all in files you control.

Boring engineering. On purpose.

Built the same way, every time

Every Tynkr app follows the same contract with you. No exceptions, no asterisks, no "premium tier" that changes the rules.
