Privacy Policy
Last updated
Scope
This policy describes information handled when you visit resin-ledger.com, contact us, or use an interactive tool.
Information we may collect
| Possible category | Example fields | Collection source | Final status |
|---|---|---|---|
| Server and security logs | IP address, request time, URL, browser/user agent, security events | Hosting, CDN, security provider | Processed by Cloudflare as host. Not retained by us: this deployment enables no log retention or export |
| Email correspondence | Your email address and message | Email routing and destination mailbox | Sent to the destination mailbox when you email us; no site form |
| Analytics data, if allowed | Page views, referral source, device and approximate location | Google Analytics 4 | Collected only after you allow the analytics category |
| Privacy choice | Analytics choice and date/time | This browser's local storage (rl-consent) |
Stored in this browser until changed or cleared; not sent to our server |
| Calculator inputs | Water hardness, household assumptions, settings | This browser only | Local-only, verified: values stay in the browser and are never stored or transmitted |
How information may be used
Subject to the verified inventory, information may be used to:
- deliver pages, calculators, downloads, and requested responses;
- maintain security, prevent abuse, and diagnose errors;
- understand aggregate site performance;
- maintain consent and privacy preferences;
- respond to privacy requests and maintain the choice stored in your browser;
- meet legal obligations and enforce site terms.
Analytics is optional and depends on your consent. Google Analytics loads only after you allow it. Cloudflare handles requests needed to serve the pages. Email you send is used to respond to you. Applicable law determines the legal basis for these activities.
Disclosures to service providers and other recipients
| Recipient | Service | Data categories | Processing location | Contract / transfer mechanism | Retention or deletion setting |
|---|---|---|---|---|---|
| Cloudflare, Inc. (hosting and content delivery) | Site delivery and security | IP address, request time, URL, and other traffic data | Cloudflare's global network; Cloudflare states it stores information primarily in the United States and the European Economic Area | Cloudflare Data Processing Addendum version 6.4, effective April 3, 2026: EU Standard Contractual Clauses, UK International Data Transfer Addendum, Swiss adaptation | Set by Cloudflare under its own policy. We enable no log retention or export, so none of it reaches us |
| Cloudflare Email Routing (contact@resin-ledger.com) | Contact requests | Your message and your email address | Cloudflare Email Routing, which forwards it to the operator's mailbox | Cloudflare Data Processing Addendum version 6.4, effective April 3, 2026 | Destination mailbox retention period not yet verified |
| Google Analytics 4 | Audience measurement | Page views, referral source, device and approximate location | Google, per its own terms | Not verified for this account | Account setting not yet verified |
| Resin Ledger (built in, first party) | Consent collection and records | Your cookie choice and its date | Your browser only | Not applicable | Until changed or browser storage is cleared |
Retention
Calculator inputs are not stored or sent by the site. Your privacy choice remains in this browser until you change it or clear this site's storage. Email you send is kept in the destination mailbox; its retention period has not yet been verified. Cloudflare handles requests under its own privacy policy. If you allow analytics, Google Analytics receives measurement data under this property's account settings; the account-specific retention period has not yet been verified.
Security
Resin Ledger is a static site with no account or contact form. The browser stores your privacy choice, and an email you send is held by the destination mailbox. Cloudflare handles page requests. Pages are served over HTTPS with a certificate provisioned by Cloudflare. No third-party code runs on any page until you allow it, and the build refuses to publish if it finds a script, a network call, or any use of browser storage that has not been declared. Calculator entries never leave your browser.
No site and no transmission over the internet can be promised to be absolutely secure. If you find a security problem, write to contact@resin-ledger.com.
International processing
Resin Ledger is served from Cloudflare's global network, so your request is handled by whichever Cloudflare location is nearest to you, wherever you are. Cloudflare states it stores information primarily in the United States and the European Economic Area.
Cloudflare describes its transfer measures in the Cloudflare Data Processing Addendum, version 6.4, effective April 3, 2026, which incorporates the EU Standard Contractual Clauses, the UK International Data Transfer Addendum, and the Swiss adaptation. Google Analytics and email providers handle other information described above under their own terms.
Privacy rights and choices
Privacy rights depend on where you live. You can use the Privacy Choices link in the footer to withdraw analytics permission; this stops future analytics activity on this browser but does not erase data already received by Google. You can clear this site's browser storage to remove your saved choice, or email us about correspondence you sent. The site has no accounts. Cloudflare and Google Analytics may hold data under their own services, so a request about those data must be assessed against the actual provider settings and applicable law.
Requests: email to contact@resin-ledger.com
Identity verification and authorized agents: we reply to the address the request came from. There is no account to match you against. We may ask for enough information to locate the correspondence you ask about, without requesting unnecessary identity documents.
Appeals, if applicable: if we turn a request down, reply to the same address and say so. A person reads it again and tells you why. Some U.S. state privacy laws also let you complain to your state attorney general.
Withdrawing consent does not affect processing that was lawful before withdrawal.
Children
Resin Ledger is written for adults who own, are buying, or are troubleshooting a home water softener. It is not directed to children, and we do not knowingly collect information from anyone under 13.
There is very little that could be collected in the first place: no accounts, no forms, no profile of any kind. If you believe a child has sent us something by email, write to contact@resin-ledger.com and we will delete it.
External links
Resin Ledger may link to third-party sites. Their privacy practices are governed by their own policies. A link does not make their practices ours.
Changes
When this policy changes, the Last updated date at the top of this page changes with it. There is no mailing list here to write to, so the page is the notice: if that date is newer than the last time you read this, the text is not the text you read.
The date is not typed in by hand each time and left to drift. The build fingerprints the text you are reading and refuses to publish it if the fingerprint has moved and the date has not.
