Jet Set Go! — Privacy

Tue, 21 Jul 2026 00:00:00 +0000

This is the per-product privacy policy for Jet Set Go! It supplements the global privacy policy; if anything here conflicts with the global policy, the more specific statement on this page wins for this product.

Data we collect

None. Jet Set Go! runs entirely offline. The game does not transmit any data off the device — no analytics, no crash reports, no telemetry, no advertising identifiers, no account system.

Game progress and high scores are stored locally on the device and never leave it. Uninstalling the app removes all stored data.

SDKs and third-party services

This product ships no third-party SDKs. No analytics. No crash reporting. No advertising networks. No app measurement. No third-party authentication.

The only third-party surface involved in the product is the App Store / Play Store distribution itself, which is governed by Apple’s and Google’s own agreements with you.

Permissions

Jet Set Go! requests no device permissions. The game does not access your camera, microphone, location, contacts, photos, storage, or any other sensitive system resource.

Children’s privacy

Jet Set Go! is rated 4+ on the App Store and Everyone on Google Play. The game contains no user-generated content, no chat, no online features, and no advertising. There is no mechanism by which a child using the app could expose personal data, because the app handles no personal data.

Game Center / Play Games compatibility

Jet Set Go! does not integrate with Apple Game Center or Google Play Games. Leaderboards and ghost replays are stored locally only. If a future version adds Game Center / Play Games integration, this policy will be updated before that version ships, and the relevant platform’s privacy practices will apply to the synced data.

Changes to this policy

When the product’s data practices change, this page will be updated and the “Last updated” date bumped. Past versions are in the public git history.

Email privacy@denotatum.com with any questions about Jet Set Go!’s privacy practices. We aim to respond within a week.

Terms of Service

Tue, 21 Jul 2026 00:00:00 +0000

These terms govern your use of denotatum.com and the apps and games we publish. By using any of them, you agree to what follows. If you do not agree, do not use the site or the products.

We try to keep this readable. Where a clause has to be precise to be enforceable, we use the precise language and explain what it means in plain English right after.

1. Who we are

denotatum-technologies is the trading name under which Tim Willis publishes apps and games. For legal correspondence, email legal@denotatum.com.

2. Your license to use this website

We grant you a personal, non-exclusive, non-transferable, revocable license to access denotatum.com for your own browsing. That is, you can read the site. You cannot:

Republish the site’s content (text, images, markup) elsewhere without permission.
Scrape, mirror, or otherwise hammer the servers.
Bypass any access control, even one as trivial as a robots.txt directive.
Use the site in a way that breaks any law or third-party right.

The site’s source code is public on GitHub where noted. Where it is, the applicable open-source license (linked from the repo) takes precedence over this section for the source itself.

3. Your license to use our apps and games

Apps and games are distributed through Apple’s App Store and Google’s Play Store. The store’s own end-user license agreement applies to your use of the app — that is the contract under which you licensed the binary. Where the store’s terms and our terms conflict on app behavior, the store’s terms control.

For clarity: we license the app to you, we do not sell it. You own the device; we own the software. Standard app-store model.

4. Acceptable use

Do not:

Reverse engineer, decompile, or disassemble our binaries beyond what applicable law explicitly permits for interoperability.
Cheat, bot, or otherwise break competitive features in any game that ships online leaderboards, ghost replays, or multiplayer.
Reskin, repackage, or relist our apps under a different name.
Use our trademarks (denotatum-technologies, Jet Set Go!, and related marks) without written permission, except as fair use to refer to us or our products.

5. Intellectual property

The site content, the games, the source where published, the names, the logos, the artwork, the music — all of it is either ours or used with permission. We retain all rights not expressly granted in these terms.

If you believe something on the site or in a product infringes your copyright, email legal@denotatum.com with the details. We will respond within a reasonable time.

6. Third-party services

The site is hosted by Netlify. The apps are distributed by Apple and Google. Each of those providers has its own terms, privacy practices, and policies — we are not responsible for them, and your use of their services is governed by their agreements with you.

Our Privacy Policy explains what we (and only we) collect. It is much shorter than this page.

7. Disclaimer of warranties

The site and the apps are provided “as is” and “as available”, without warranties of any kind, express or implied. We do not promise the site will be uninterrupted, error-free, or safe from every possible bug. We do not promise the apps will run on every device forever or that they will suit any particular purpose.

Where applicable law does not allow us to disclaim implied warranties (such as merchantability or fitness for a particular purpose), those disclaimers apply only to the maximum extent permitted by law.

8. Limitation of liability

To the maximum extent permitted by law, denotatum-technologies and Tim Willis are not liable for any indirect, incidental, consequential, special, or punitive damages arising out of your use of (or inability to use) the site or any app. Our total liability for any claim arising from these terms or your use of the site or apps is limited to the amount you paid us in the twelve months before the claim, which — because our products are either free or paid through app stores under their own terms — is almost always zero.

This clause exists because it has to. In practice, if we break something you relied on, email us and we will work it out.

9. Governing law

These terms are governed by the laws of the State of Mississippi, without regard to its conflict-of-law rules.

10. Changes to these terms

We may update these terms. When we do, we will bump the “Last updated” date at the top of this page. Past versions are available in the public git history.

If a change is material (new restriction, new liability shift, etc.), we will call it out in the page body, not just silently rely on the date.
