Privacy Policy

Last updated: 2026-04-17

This policy explains what data Kefiw collects, why, and what we do with it. It is intentionally short.

The short version

• We do not require an account and do not know who you are.
• We do not sell personal data. We do not have personal data to sell.
• Most tools run entirely in your browser. What you type into them stays on your device.
• Some games save progress to your device’s local storage. You can clear it from your browser at any time.

Analytics

We may use a privacy-focused, cookie-less analytics provider (such as Cloudflare Web Analytics) to understand how many people visit Kefiw and which tools are used. This records aggregate information (country, browser family, referring site, page views) and does not identify individual visitors.

Advertising

Kefiw may display ads from a third-party ad network on some pages to keep the service free. If enabled, those networks operate under their own privacy policies and may use cookies or similar technologies to measure impressions. You can usually opt out of personalised advertising in your browser or operating system settings.

Local storage

Kefiw stores small amounts of data locally in your browser so you don’t lose game progress or preferences between visits. Examples include the current Sudoku puzzle state. This data never leaves your device.

Cookies

Kefiw itself does not set tracking cookies. Third-party scripts (if any) may do so under their own policies.

Children

Kefiw is suitable for general audiences. We do not knowingly collect data from anyone.

Changes

We may update this policy. Material changes will be reflected by updating the “Last updated” date above.
