Privacy Policy

Nagomi is made by Mayank, an independent developer based in India (“we”, “us”). This policy covers the Nagomi app and this website, nagomi.m4yank.com. For anything about your data, email nagomisupport@m4yank.com.

Nagomi has no analytics, no tracking, no ads and no crash reporting. The pond runs entirely on your computer. It only goes online for two things:

• Your license, through Polar. When you paste your license key, the app sends it to Polar to activate it on this computer, along with an ID for this computer (a one-way hash of its hardware ID, so the hardware ID itself can't be read from it), and then checks it about once a week. Polar keeps a record of the activation so your license can be moved between computers.
• Moving your license, through this website. When your key is already in use on as many computers as it allows, the app sends the key to nagomi.m4yank.com, which asks Polar where it's in use and passes back each activation's date and computer ID, so you can move it. We don't store the key or the answer.
• Updates, from cdn.m4yank.com. The app asks for the latest version shortly after it opens and then once a day. The files are served by Cloudflare, which, like any web server, sees your IP address and may keep it in short-lived logs.

Your email, license key and activation ID are saved in the app's settings folder on your computer, so it can stay signed in. They aren't sent anywhere else. Your settings, themes and koi stay on your computer.

• Hosting. The site is hosted by Vercel, which processes standard request data such as your IP address to serve pages and keep the site secure.
• Page counts. We use Vercel Web Analytics to count page views and see which pages people visit. It doesn't use cookies and doesn't identify you or follow you to other sites.
• The Windows list. If you join the list for Windows, we store your email and your country (worked out from your IP address; the address itself isn't kept) in Supabase. We use it only to email you when Nagomi for Windows is ready.
• Your license key. After you buy, the thank-you page reads your purchase from Polar to show your license key, and sets two cookies so this site can show it again when you come back: one holds a signed reference to your customer record at Polar, the other only notes that you bought. They last a year. Choose Sign out of this browser on the thank-you page to remove them.
• Support emails. If you email us, we keep the conversation so we can help you.

Nagomi is sold through Polar, the merchant of record. Polar handles checkout, payment, tax and receipts, and its own privacy policy applies to that.

We never see your card details. From Polar we see what a seller needs: your name, email, country, what you bought and when, and your license activations.

We use the information above only to:

• sell you Nagomi, let you activate it, and show you your license key;
• deliver updates;
• answer your support emails;
• tell you when Windows is ready, if you asked;
• keep the site working and secure.

We don't sell your data, share it for advertising, or send marketing emails you didn't ask for.

Only the services that run Nagomi, each for its own job above:

• Polar: payments, receipts and licenses;
• Vercel: website hosting and page counts;
• Supabase: the Windows list;
• Cloudflare: app downloads and updates.

We may also share information if the law requires it. These services may process data outside your country, including in the United States.

• Windows list: until we've sent the launch email, or sooner if you ask us to remove you.
• Purchase and license records: kept by Polar for as long as your license is in use and as the law requires for sales records.
• Support emails: as long as needed to help you.

You can ask us to show you, correct, export or delete the information we hold about you, or to take you off the Windows list. Email nagomisupport@m4yank.com and we'll reply within 30 days.

Depending on where you live (for example under the GDPR in the EU and UK, or the CCPA in California), you may have more rights, including the right to complain to your local data protection authority.

To stop the app contacting Polar, sign out in Settings → License. The pond pauses until you sign in again.

This site doesn't use cookies for tracking or advertising. If you buy Nagomi, it sets the two cookies described above so it can show you your license key; nothing else reads them. Polar's checkout may set its own cookies to complete your payment.

Nagomi isn't directed at children under 13, and we don't knowingly collect their information. If you think a child has given us their details, email us and we'll delete them.

If this policy changes, we'll update it here and change the date at the top. For important changes, we'll also say so in the app or by email.
