Frequently Asked Questions

Are all the tools on Praticulus really free?

Yes. Every tool is 100% free: no sign-up, no paywall, no usage limits.

Do you store or log the data I paste into the tools?

No. All tools run entirely in your browser: nothing is sent to any server. Your data never leaves your device.

Can I use Praticulus offline?

Most tools work after the first load since all logic is client-side JavaScript. Load the page once online, then you can keep using it offline.

Why no ads or sign-up forms?

Praticulus is part of Iris Digital, a portfolio of useful products. We prefer keeping it clean and fast over monetizing through ads or data collection.

Can I suggest a new tool?

Yes, reach out via Iris Digital. We add new tools regularly based on feedback from developers and power users.

Is Praticulus open source?

Yes. Praticulus is MIT-licensed, and the full source is public at github.com/jamalofski/praticulus. Audit it, fork it, or contribute.
