CryptoSerenity is operated by Tech Serenity Trading Company (tstcoman.com), based in Muscat, Oman. We are committed to protecting your privacy. This policy explains what data we collect, why, and how it is used.
Consent and cookie choices
When you first visit CryptoSerenity, a consent banner appears asking for your permission before we load any tracking or advertising scripts. You can choose:
Accept all — enables Google Analytics (usage statistics) and Google AdSense (ads).
Essential only — no tracking or ad scripts load. The site works fully.
Manage preferences — toggle Analytics and Ads independently.
Your choice is stored in your browser's localStorage under the key cryptoserenity.consent.v1. No consent data is sent to our servers.
We honour the Global Privacy Control (GPC) signal. If your browser sends a GPC opt-out header, all non-essential scripts are suppressed automatically, without showing the banner.
Withdraw or change consent
You can change your cookie preferences at any time. Clicking the button below clears your stored consent and reloads the page, which re-shows the consent banner.
Data we collect
Most CryptoSerenity tools operate entirely in your browser — no text you type or paste is ever sent to our servers. If you have given analytics consent, Google Analytics (GA4) collects anonymised usage data such as pages visited, time on page, and general location (country/city level). IP addresses are anonymised before storage. This data is aggregated and never personally identifiable.
Google AdSense
If you have given advertising consent, we display ads via Google AdSense. Google may use cookies to show you relevant ads based on your browsing history. You can manage personalised advertising preferences at g.co/adsettings. We do not control the data collected by Google AdSense directly. No AdSense scripts are loaded unless you have explicitly consented.
Strictly essential local storage
The portfolio tracker stores your holdings in your browser's localStorage — this data never leaves your device and does not require consent. Other preferences (theme, tool state) are stored the same way. This storage is functional, not tracking.
Cookies
We do not set our own cookies. If you consent, Google Analytics and Google AdSense may set cookies on your device. You can clear or block cookies at any time through your browser settings, or use the 'Withdraw consent' button above.
Third-party links
CryptoSerenity may link to third-party websites (such as techserenityit.com). We are not responsible for the privacy practices of those sites.
Children's privacy
CryptoSerenity is not directed at children under 13. We do not knowingly collect any personal data from children.
Your rights
Under GDPR and similar regulations, you have the right to access, correct, or request deletion of any personal data we hold. Since we collect no personally identifiable data directly, there is typically nothing to delete. For questions, contact us via techserenityit.com/#contact.
Changes to this policy
We may update this policy from time to time. The date at the top of this page reflects the latest revision. Continued use of CryptoSerenity after changes constitutes acceptance of the updated policy.
