What happens after I buy SafeJSON Pro?

Lemon Squeezy sends a SafeJSON Pro license key by email. Open the SafeJSON unlock page, paste the license key, and the browser is activated for Pro tools.

How many devices can use one SafeJSON Pro license?

Each SafeJSON Pro license can be activated on up to 2 devices.

Does SafeJSON Pro upload my JSON, JWT, or schema data?

SafeJSON Pro tools use the same browser-local JSON workflow as the free tools. Payment and license activation happen through Lemon Squeezy, but pasted JSON, JWTs, JSONPath queries, and schemas are not sent to analytics.

SafeJSON Pro questions

What happens after checkout?

Lemon Squeezy redirects you back to SafeJSON and emails your license key. Paste that key on the unlock page to activate Pro in this browser.

Can I use Pro on more than one device?

Yes. Each license supports up to 2 device activations, so you can use it on your main browser and one backup device.

Do Pro tools keep the same privacy boundary?

Yes. Diff, JWT Decoder, JSONPath, and Schema Validator keep the no pasted-content upload boundary for core tool operations. License activation is the server-backed step.

Core tool operations use a browser-local workflow with no pasted-content upload. Payment is handled by Lemon Squeezy; SafeJSON does not receive your payment details.
