Privacy Policy

Last updated: June 30, 2026

GMT Optimizer ("we", "us", "the tool") is a free, independent calculator and projection tool for GoMining users, available at gmt-optimizer.com. This policy explains what personal data we collect, why, and what rights you have. We aim to collect as little as possible.

Information we collect

Information you give us. If you use our "claim your funded TH" form, we collect the details you submit: your name or handle, your GoMining username, your chosen contact method (such as an email address, Telegram, or X handle), and any optional message. You provide this voluntarily.

Information stored only in your browser. The tool saves your preferences (such as display currency and whether you have completed onboarding) in your browser's local storage. This data stays on your device and is not transmitted to us.

We do not run advertising trackers, and the calculator does not require an account or login.

How we use your information

To respond to you and, where applicable, to fulfil the new-user offer (funding your first TH and helping you set up your account).
To provide support and answer questions you send us.
To prevent abuse of our offers (for example, verifying a genuine sign-up).

We do not sell your personal data.

Service providers

We use third-party services to operate the site. When you submit the claim form, your submission is processed and stored by Formspree so we can read and reply to it — see the Formspree Privacy Policy. The site itself is hosted on GitHub Pages, which may process technical information such as IP addresses in its server logs. Live market data shown in the calculator is fetched from third-party data sources.

Data retention

We keep claim-form submissions for as long as needed to process your request and administer the offer, after which we delete them. You may ask us to delete your data at any time.

Your rights

Depending on where you live (including under UK/EU GDPR and similar laws), you may have the right to access, correct, delete, or restrict the use of your personal data, to object to processing, and to data portability. Where we rely on your consent, you can withdraw it at any time. To exercise any of these rights, contact us using the form below.

Security

We take reasonable measures to protect the limited data we hold, but no method of transmission or storage over the internet is completely secure, and we cannot guarantee absolute security.

Children

GMT Optimizer is not intended for anyone under 18, and we do not knowingly collect data from children.

Changes to this policy

We may update this policy from time to time. Material changes will be reflected by the "Last updated" date above.

For any privacy question or data request, please use the contact form on our homepage and we will get back to you.
