Frequently asked questions
Is Nonkera really free to use?
Yes. All tools available today are completely free with no usage limits. In the future we may add optional premium features, but the core toolset will always remain free.
Why does Nonkera show ads?
Ads are how we keep every tool free with no account, paywall, or usage limit — running and building Nonkera has real costs, and advertising covers them instead of charging you. Ads are placed only in clearly marked areas of the page and never inside a tool's own interface, and we only enable personalized ads if you opt in through our cookie consent banner. See our Privacy Policy for the full details.
Do I need to create an account?
No account is required to use any tool. We're preparing optional accounts for a future release so you can save preferences and history, but it will never be required.
Is my data private?
Yes. Wherever technically possible, Nonkera processes your files and text directly in your browser — they are never uploaded to our servers. See our Privacy Policy for full details.
Is Nonkera accessible for people with disabilities?
We build Nonkera to follow WCAG 2.1 AA accessibility guidelines — keyboard-friendly navigation, screen reader support, and sufficient color contrast throughout. See our Accessibility Statement for details on our approach, and how to report a problem.
What devices and browsers are supported?
Nonkera works on any modern desktop or mobile browser, including Chrome, Safari, Firefox, and Edge. No app or plugin installation is required.
Will more tools be added?
Yes — we're actively expanding the tool library every month. If there's a tool you'd like to see, reach out through our Contact page.
