Privacy Policy

Oh My Maps! is a free, browser-based map editor. This page explains what happens to your data when you use it — in plain language, because the actual story is simple.

The short version

Your map never leaves your browser unless you explicitly export it or create a share link. There are no accounts, no sign-up, and no server that stores your map. We use two analytics services to see how many people visit, and neither uses cookies.

No accounts

Oh My Maps! has no sign-up, no login, and no user accounts of any kind. Nothing on the site requires or supports one.

Your map lives in your browser only

Everything you do in the editor — painting regions, choosing colours, adding labels, adjusting zoom — is stored using your browser’s own localStorage, scoped to your device and browser. It is never uploaded to a server, never synced across your devices, and never seen by us. If you clear your browser’s site data, it’s gone; we have no copy to restore it from.

Two features let you move a map off your own device, and both work entirely on your side, with no server involved:

• Save file downloads a .json file of your map to your own disk.
• Share link compresses your whole map into the URL itself. Anyone who opens that link decodes the map in their own browser — nothing is stored on our servers to make sharing work.

Exported images (PNG, JPEG, WebP, SVG) are also rendered entirely in your browser and are never uploaded anywhere.

We also store two small, unrelated preferences locally: your theme choice (light/dark) and your language choice. Both are plain localStorage values on your device and are never transmitted anywhere.

Analytics

We use two analytics services to understand overall traffic. Both are cookie-less — there are no cookies anywhere on this site.

• Cloudflare Web Analytics — aggregate, anonymised traffic data. No cookies, no personal data collected.
• Umami (cloud-hosted) — also cookie-less by default. We additionally generate a random identifier (via crypto.randomUUID()) that’s stored in your browser’s localStorage under the key maps:visitor-id and sent to Umami. This exists solely so that a returning visitor is counted once across sessions, instead of registering as a brand-new visitor every time their IP address happens to change (which is how Umami’s default visitor-counting works, and it was inflating our numbers). This identifier carries no name, email, or other personal information, and it is never used to track you across other sites or to serve ads — only to count visits to this site accurately.

Both services receive only anonymous, aggregate information: page views, the identifier above, and coarse browser/OS/country-level data. They never receive anything about the content of your map or anything you’ve typed or drawn.

No ads, no selling data, no third-party sharing

There are no third-party ads on this site. We don’t sell any data, and we don’t share any data with third parties beyond the two analytics processors named above, who only ever receive the anonymous, aggregate usage information described.

Map data sources

The map geometry itself (country and region borders) comes from Natural Earth, which is public domain. This isn’t personal data and has no bearing on your privacy — it’s just worth knowing where the shapes on the map come from.

Changes to this policy

If this policy changes, we’ll update the “last updated” date at the top of this page.
