FAQ
Common questions
Is Synctoolo really free?+
Yes. Every tool on the site is 100% free. No signup, no credit card, no hidden tier. The project is supported by optional Patreon memberships and minimal sponsorships.
Are my files and inputs safe?+
Most utility tools (JSON formatter, Base64, regex tester, etc.) run entirely in your browser. Nothing is uploaded. For AI tools, inputs are processed and immediately discarded.
Do I need an account?+
Never. Synctoolo is built to work the moment you land on a page. Favorites and recents are stored locally on your device.
How do you make money?+
We don't, really. The site is sustained by optional Patreon support and occasional ethical sponsorships. If a tool saved you time, consider joining on Patreon!
