Privacy Policy
Last updated: 2026-10-13 · Effective date: 2026-05-06
Stability Protocol ("we", "us", "our") operates the website stabilityprotocol.space (the "Service"). This Privacy Policy explains what information we collect, how we use it, with whom we share it, how long we keep it, and the rights you have over it. By using the Service you acknowledge that you have read this Privacy Policy.
1. Data Controller
For the purposes of the EU General Data Protection Regulation (GDPR), the UK GDPR, and similar laws, the data controller is Stability Protocol. Privacy questions and rights requests should be directed to [email protected].
2. Information We Collect
We are a free, no-signup Zakat calculator. We collect the minimum amount of data needed to deliver and improve the Service.
2.1 Information you actively provide
None by default. The Zakat calculator runs entirely in your browser. The amounts, weights, and asset values you enter are processed locally on your device and are never transmitted to our servers.
2.2 Information collected automatically
- Server and security logs processed by Cloudflare on our behalf: IP address, request timestamp, user-agent, page requested, referrer, and approximate country derived from IP. Used solely to deliver content, prevent abuse, and detect attacks.
- Aggregated analytics (page views, country, browser, device class) collected via Cloudflare Web Analytics: privacy-first, cookie-less, no personal data.
- Optional analytics signals: only after you consent through the cookie banner. Google Analytics 4 may use cookies and pseudonymous identifiers. Google AdSense and conventional advertising networks are excluded by our Halal Charter.
3. How We Use Your Information
- To operate, secure, and improve the Service.
- To produce aggregated, non-identifying usage statistics.
- To measure site use and clicks on affiliate links, only if you consent to analytics.
- To comply with legal obligations and respond to lawful requests.
We do not sell your personal information. We do not use the financial values you enter into the calculator for any purpose: they never leave your device.
4. Legal Basis for Processing (GDPR / UK GDPR)
- Legitimate interests (Article 6(1)(f)): for security logs, fraud prevention, and aggregated, privacy-preserving analytics.
- Consent (Article 6(1)(a)): for Google Analytics cookies and measurement. Withdraw it at any time using Cookie preferences in the footer.
- Legal obligation (Article 6(1)(c)): when we must retain or disclose information to comply with applicable law.
5. Third-Party Services and Recipients
We share limited information with the following processors, each governed by its own privacy policy:
- Cloudflare, Inc.: hosting (Cloudflare Pages), CDN, DDoS protection, and privacy-first Web Analytics. Processes IP addresses for routing and security. Cloudflare Privacy Policy.
- Google LLC: Google Analytics 4 (GA4). Loaded only after consent.
May set first-party cookies (e.g.
_ga,_ga_*) and process pseudonymous identifiers, page paths, and approximate location (IP-based, anonymized). Google Privacy Policy. - Google AdSense and conventional advertising networks are not used. See our Halal Charter.
- Metal price data is fetched from a Stability Protocol-operated
Cloudflare Worker (
metal-prices.stachboo.workers.dev) that proxies public gold/silver price feeds. The request contains no identifying data beyond your IP.
6. International Data Transfers
Cloudflare and Google process data in the United States and other countries outside the European Economic Area (EEA), the United Kingdom, and Switzerland. Where required, these transfers rely on appropriate safeguards including the European Commission's Standard Contractual Clauses (SCCs) and the EU-US Data Privacy Framework (DPF) for participating recipients.
7. Cookies and Consent Management
The consent cookie remembers your choice. Google Analytics 4 is loaded only after you accept analytics. Before that choice, and after refusal, this site does not load the Google Analytics tag. Advertising consent stays denied.
Change or withdraw analytics consent using Cookie preferences in the footer. Withdrawal clears this site's accessible Google Analytics cookies and reloads the page to stop the loaded tag.
8. Data Retention
- Cloudflare server logs: up to 30 days for security purposes.
- Cloudflare Web Analytics: up to 6 months in aggregated form.
- Google Analytics 4: data retention configured at the GA4 maximum allowed for our property (default 14 months).
- Consent records: kept as long as necessary to demonstrate compliance, typically 24 months.
9. Your Rights (GDPR / UK GDPR)
Where we process your personal data, you have the right to: access, rectify, erase, restrict processing, object to processing, request portability, and withdraw consent at any time. To exercise any right, contact [email protected]. We will respond within one month.
You also have the right to lodge a complaint with a supervisory authority: for example the CNIL in France (cnil.fr), or the data protection authority in your country of residence.
10. California Privacy Rights (CCPA / CPRA)
If you are a California resident, the California Consumer Privacy Act as amended by the California Privacy Rights Act ("CCPA/CPRA") gives you the right to know what personal information we collect, to request deletion, to correct inaccurate information, and to limit the use of "sensitive personal information". You also have the right to opt out of the "sale" or "sharing" of personal information for cross-context behavioral advertising.
We do not sell personal information. We do not use Google AdSense or cross-context behavioral advertising. You can refuse optional Google Analytics measurement using Cookie preferences in the footer.
11. Children's Privacy
The Service is not directed to children under 16, and we do not knowingly collect personal information from them. If you believe a child has provided us with personal information, please contact us and we will delete it.
12. Security
We rely on Cloudflare's enterprise-grade infrastructure, enforce HTTPS everywhere, apply a strict Content Security Policy, and minimise data collection by design (the calculator is client-side). No method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.
13. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. The "Last updated" date at the top reflects the most recent change. Material changes will be highlighted on the homepage or through the cookie banner.
14. Language Versions
This Privacy Policy is published in English, French, Arabic, and Urdu. In case of any discrepancy or conflict between language versions, the English version prevails.
