Privacy
How ChemStore Checker handles your data.
Last updated: 2026-05-03
Introduction
This privacy policy explains how household-chemical-storage-compat-checker.hub2.day (“ChemStore Checker”, “the site”, or “we”) handles information when you use our compatibility checker for household chemical storage. The site is a focused, independent web utility that helps visitors identify dangerous storage pairings among common household chemicals and recommends safer storage zones.
Information We Collect
Browser-Local Inputs
The chemical names, categories, and storage-zone selections you enter into the checker are processed in your browser to generate compatibility results. We do not transmit your specific chemical lists or storage configurations to our servers by default. Where optional features (for example, saving or sharing a configuration) require temporary server processing, we disclose that clearly at the point of use and limit retention to the minimum necessary.
Contact Email
If you contact us at hello@household-chemical-storage-compat-checker.hub2.day, we will use your email address and message content solely to respond to your inquiry. We do not add contact emails to marketing lists without your explicit consent.
Server and Security Logs
Our hosting and security infrastructure may automatically record limited technical information when you access the site, such as IP address, request timestamps, requested URLs, HTTP status codes, and basic device/browser characteristics. These logs are used for security, abuse prevention, troubleshooting, and basic performance monitoring.
Cookies and Local Storage
We may use cookies and similar technologies (including browser local storage) for:
- essential site operation (for example, remembering your consent preferences),
- basic usage analytics, and
- delivering and measuring advertisements via Google AdSense.
Where required by law, we ask for your consent before setting non-essential cookies or similar technologies.
Google AdSense and Advertising
ChemStore Checker uses Google AdSense to display advertisements. Google and its partners may use cookies and similar technologies to serve ads based on your prior visits to this site or other sites, and to measure ad performance.
Google may collect and use data such as:
- cookie identifiers and similar online identifiers,
- information about your browser, device, and approximate location (for example, derived from IP address), and
- interactions with ads and pages on this site.
You can learn more about how Google uses data and manage your preferences through Google’s ad settings and privacy policy.
GDPR, EEA, and UK Consent
If you are located in the European Economic Area (EEA), the United Kingdom, or another jurisdiction with similar laws, we rely on appropriate legal bases to process personal data, such as:
- your consent (for example, for non-essential cookies or advertising),
- our legitimate interests (for example, security, fraud prevention, and site improvement), or
- performance of a contract or pre-contractual steps (for example, responding to your requests).
Where we rely on consent, you may withdraw it at any time through the cookie or consent controls provided on the site, or by contacting us.
CCPA / CPRA Rights (California Residents)
If you are a California resident, you may have rights under the CCPA/CPRA, including the right to:
- know what personal information we collect and how it is used,
- request deletion of certain personal information,
- opt out of the “sale” or “sharing” of personal information as defined by law, and
- non-discrimination for exercising your rights.
To exercise these rights, please contact us at hello@household-chemical-storage-compat-checker.hub2.day. We may need to verify your identity before fulfilling your request.
Service Providers
We may share limited information with service providers that help us operate the site, such as hosting providers, security services, and advertising partners like Google AdSense. These providers are contractually required to use your information only for the purposes we specify and to maintain appropriate security measures.
Data Retention
We retain personal data only as long as necessary for the purposes described in this policy, or as required by law. For example:
- contact emails and related correspondence are retained as long as needed to handle your request and for reasonable record-keeping,
- server and security logs are retained for a limited period appropriate to security and operational needs, and
- cookie and local storage data are retained according to their configured lifetimes and your consent choices.
Children’s Privacy
ChemStore Checker is not directed to children under 13 (or the applicable age of consent in your jurisdiction). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can take appropriate steps.
Security
We implement reasonable technical and organizational measures to protect information against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission over the Internet or method of electronic storage is completely secure, and we cannot guarantee absolute security.
Third-Party Links
The site may contain links to third-party websites, resources, or services. We are not responsible for the privacy practices or content of those third parties. We encourage you to review their privacy policies before providing personal information.
International Processing
Your information may be processed in countries other than your country of residence, including the United States. Where required, we take steps to ensure that appropriate safeguards are in place for international data transfers.
Changes to This Policy
We may update this privacy policy from time to time. When we do, we will update the “Last updated” date at the top of this page. Continued use of the site after changes indicates your acceptance of the revised policy.
