Cookie Policy
This policy explains what is (and is not) stored on your device when you use Gem TD or this site. The honest summary: there are no tracking or advertising cookies here today. The game keeps some data in your browser so it can remember your progress, but that stays on your device.
1. Cookies used today: none for tracking
As of the “Last updated” date above, this site and the game set no analytics, advertising, or third-party tracking cookies. I do not run ad networks, and I do not profile visitors. If a strictly-necessary cookie is ever needed for core functionality (for example, to complete a secure checkout through the payment processor), it would be used only for that purpose and would not track you across sites.
2. Local storage the game needs
Gem TD saves your progress using your browser’s localStorage. This is technically
not a cookie — it is not sent to any server with your requests — but I
disclose it here for transparency because it does store data on your device. It is used purely to
make the game work: to remember where you are and what you have unlocked.
| What is stored | Where | Purpose |
|---|---|---|
| Campaign progress & unlocks | localStorage (your device) | Resume the game where you left off |
| High scores | localStorage (your device) | Show your best results |
| Settings & preferences | localStorage (your device) | Remember options such as audio and display |
This data is never transmitted to me and is not linked to your identity. See the Privacy Policy for more.
3. Managing local data
You are in control. Clearing your browser’s site data (or using private/incognito mode) removes the stored game data — which also resets your progress and scores. Most browsers let you clear storage for a single site from their settings or site-information menu.
4. If this changes
If I later add analytics or any non-essential cookies, I will update this policy first, describe the categories in use, and present a consent banner or control where the law requires one — before any such cookie is set.
