Privacy Policy

Last updated: November 2026

This policy explains what fishsymptoms.com ("we", "the site") does with data when you visit. Plain-language summary: we run ads and analytics, we have an optional email signup, we use affiliate links, and we do not sell your personal data. Details below.

1. Google AdSense and third-party advertising cookies

This site displays advertising served by Google AdSense (and, once enabled, other ad networks). When ads are shown:

• Google and its third-party ad vendors (networks) may use cookies to serve ads based on your prior visits to this or other websites.
• Google's use of advertising cookies (including the DART cookie and equivalent identifiers) enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
• Third-party ad vendors may also use their own cookies, web beacons and SDKs to measure and personalize ads. These are set by the third parties' own domains, not by fishsymptoms.com directly.
• You can opt out of personalized advertising by visiting Google Ads Settings, or opt out of third-party vendor cookies for personalized advertising at aboutads.info/choices (US) and youronlinechoices.eu (EU).
• Where required (EEA/UK), advertising cookies are only set after consent via our cookie consent banner; you can withdraw consent there at any time.

2. Analytics

We use website analytics (Google Analytics 4, once enabled on this site) to understand aggregate usage: which guides help, which pages lose readers, what search phrases bring people here. Analytics providers set their own cookies or similar identifiers and process data such as pages viewed, approximate geolocation, device type and referrer. Data is used to improve content, is aggregated where possible, and is governed by the analytics provider's own privacy policy. Where consent is required, analytics cookies load only after you accept.

3. Amazon Associates affiliate links

Some gear pages contain Amazon affiliate links. If you click one, Amazon sets cookies on Amazon's domain to attribute your purchase to this site so we may earn a commission. That attribution data lives on Amazon's systems and is subject to Amazon's own published privacy notice, not ours. We receive no personal data from those clicks beyond anonymous attribution reporting.

4. Email signup (Formspree)

The "new tank cycle checklist" form submits your email address through Formspree, a third-party form service, which processes it under its own privacy policy so we can deliver the PDF and send occasional guide updates. We use your email only for that purpose, never sell or rent it, and every email includes an unsubscribe link. To request deletion of your address from our list, email hello@fishsymptoms.com.

5. What we do NOT do

• No accounts, no passwords, no payment data on this site.
• The symptom finder and stocking calculator run entirely in your browser — the symptoms you tick and your tank numbers are never transmitted or stored by us.
• No selling of personal data to anyone, under any definition of "sell".

6. Children

This site is a general-audience reference and is not directed at children. We do not knowingly collect personal information from children. AdSense ad serving on our site follows Google's policies, including limits on personalized ads for users under the age of consent in their region.

7. Your rights

Depending on your jurisdiction (GDPR, CCPA/CPRA, etc.) you may have rights to access, correct, delete, port or restrict processing of your personal data, and to object to processing or withdraw consent. Because the personal data we hold is minimal (mainly email-list addresses), most requests are handled immediately by emailing hello@fishsymptoms.com. We respond within 30 days.

8. Contact & changes

Questions: hello@fishsymptoms.com. When this policy changes materially, we update the "Last updated" date above. Continued use of the site after changes constitutes acceptance of the revised policy.
