Privacy Policy

Last updated: 2026-09-01

1. What this site stores

This is a static site with no account system and no server-side database of yours. The tools keep data in your browser's localStorage only:

  • sg_lang — chosen interface language
  • sg_consent — your cookie/ad-consent choice
  • sg_favorites — saved articles and tools
  • sg_weight_pets / sg_weight_records — weight tool data
  • sg_cost_plans / sg_diet_plans — saved calculator scenarios

Nothing in localStorage is transmitted to us. Clearing browser site data removes all of it.

2. Google AdSense & cookies

We may use Google AdSense to show ads. Third-party vendors, including Google, use cookies to serve ads based on your prior visits. Google's use of advertising cookies (including the DoubleClick DART cookie) enables it and its partners to serve ads tailored to you.

  • You can opt out of personalized advertising in Google Ads Settings.
  • You may opt out of some third-party vendors' personalized advertising at www.aboutads.info (Digital Advertising Alliance).

Ad scripts load only after you accept in the consent banner; before consent (or if you reject) Google Consent Mode signals are set to denied. With a placeholder publisher ID, no ad script is loaded at all.

3. Cookie table

sg_* (localStorage)First partyLanguage, consent, favorites, tool dataUntil cleared

4. GDPR / UK / EU rights

If you are in the EEA/UK, you have the right to access, rectify, erase, restrict, port and object to processing of personal data, and to withdraw consent at any time via the banner choices or by clearing site data. Because we hold no server-side personal data, most rights are exercisable directly in your browser. Complaints may be filed with your supervisory authority.

5. CCPA (California)

We do not sell personal information and maintain no account database of California residents. Third-party ad partners may act as data sellers; use the opt-out links in section 2 and your browser's Global Privacy Control where supported.

6. Children

The site is not directed to children under 13 (or the local equivalent) and we do not knowingly collect their personal data. Parents who believe a child's data was stored locally should clear the browser site data; ad personalization for under-16 users is restricted by Consent Mode defaults.

7. Email contact

If you email zjp133@outlook.com, your message and address are used only to reply. Please avoid sending sensitive personal, location or medical data. We do not import addresses into marketing lists.

8. Changes

Material updates change the "last updated" date. Continued use after an update constitutes acceptance.
