Privacy Policy
What this website collects, why, and what you can do about it. We keep data collection to the minimum an independent review site needs.
Last updated: August 28, 2026
In short
We do not sell your personal information. We do not process payments, so we never see your card details. We use basic analytics to understand which pages are read, and the sellers we link to set their own cookies to credit the referral.
1. Who we are
Water From Air Review is an independent publisher of reviews and educational content about home water security and DIY atmospheric water generation. We are not the seller of any product reviewed here.
For any privacy question, contact us at contact@energyrevolutionsystern.com. This policy applies to this website only.
2. Information we collect
2.1 Information you give us
You can read this entire website without giving us anything. We only receive personal information when you choose to send it, for example when you email us a question, submit a build report or measured output figures, or subscribe to updates. In those cases we receive your email address and whatever you include in your message.
2.2 Information collected automatically
Like almost every website, our host and analytics record technical information when you visit:
- IP address, in whole or truncated form
- Browser type and version, operating system and device type
- Pages viewed, time on page and the order in which pages were visited
- The referring website or search that brought you here
- Approximate location derived from IP address, typically at city or region level
- Date and time of the request
2.3 What we never collect
We do not collect payment card numbers, bank details or purchase records, because purchases happen entirely on the seller's platform. We do not knowingly collect sensitive categories of personal data such as health, biometric, religious or political information.
3. Cookies and similar technologies
3.1 Types in use
- Strictly necessary: keep the site secure and functioning, and remember basic preferences such as a dismissed notice.
- Analytics: count visits and page views in aggregate so we know which reviews are useful.
- Referral tracking: set by the seller and its payment processor when you click through to their site, so the visit can be credited.
3.2 Referral cookies belong to the seller
When you click a link to a seller, that seller and its processor may place cookies on your device and process data under their own privacy policies. We do not control those cookies and we do not receive your personal purchase information from them, only aggregate reporting about referred sales.
3.3 Controlling cookies
You can block or delete cookies in your browser settings, and most browsers offer a private browsing mode and a setting to reject third party cookies. Blocking analytics or referral cookies does not stop you using this website or purchasing from any seller.
4. How we use information
We use the information described above only to:
- Operate, secure and maintain the website
- Understand in aggregate which content is read, so we can improve or correct it
- Reply to your emails and, with your permission, publish a build report you send us
- Send updates if you explicitly subscribed, with an unsubscribe link in every message
- Detect and prevent fraud, abuse and technical attacks
- Comply with legal obligations and enforce our Terms of Service
We do not use your information for automated decision making that has a legal effect on you, and we do not build advertising profiles about you.
5. Legal bases for processing
Where data protection law such as the GDPR or the UK GDPR applies to you, we rely on:
- Legitimate interests for site security, fraud prevention and aggregate analytics
- Consent for non essential cookies and for marketing emails, which you may withdraw at any time
- Legal obligation where we must retain or disclose information by law
6. Sharing and disclosure
We do not sell or rent your personal information, and we do not share it for cross context behavioural advertising.
We share information only with service providers that help us run the site, and only to the extent they need it:
- Website hosting and content delivery providers
- Analytics providers, in aggregate or pseudonymised form
- Email delivery providers, if you subscribed or wrote to us
- Sellers and their payment processors, which independently record referral clicks
We may also disclose information where required by law, court order or a valid governmental request, or to protect our rights, safety or property. If the site is ever transferred to a new owner, information may pass with it under this policy.
7. International transfers
Our providers may store and process information in the United States and other countries. Where information is transferred out of your region, we rely on the safeguards offered by those providers, such as standard contractual clauses, to protect it.
8. Retention and security
We keep information only as long as it serves the purpose it was collected for. Server logs and analytics data are typically retained for up to 26 months in aggregate form. Email correspondence is kept while it remains relevant to your query, and subscription records are kept until you unsubscribe.
We use reasonable technical and organisational safeguards, including encrypted connections and restricted access to accounts. No website can promise absolute security, so please do not send sensitive information by email.
9. Your rights and choices
9.1 Rights you may have
- Access the personal information we hold about you
- Correct information that is inaccurate or incomplete
- Delete your information, subject to legal retention requirements
- Object to or restrict certain processing
- Receive a copy of information you provided in a portable format
- Withdraw consent at any time, including unsubscribing from emails
- Opt out of the sale or sharing of personal information. We do not sell or share it, so there is nothing to opt out of
- Be free from discrimination for exercising any of these rights
9.2 How to exercise them
Email contact@energyrevolutionsystern.com with your request. We respond within 30 days, or within 45 days for requests under California law, and we may ask for information to verify your identity before acting. An authorised agent may submit a request on your behalf with written proof of authorisation.
9.3 Complaints
If you are unhappy with our response, you may lodge a complaint with your local data protection authority or, in the United States, your state attorney general.
10. Do Not Track and global privacy signals
There is no common industry standard for honouring Do Not Track browser headers. Because we do not sell or share personal information or serve behavioural advertising, no opt out signal is required for that purpose. Where a recognised global privacy control signal is received, we treat it as an objection to non essential analytics cookies.
11. Children's privacy
This website is intended for adults and is not directed to children under 16. We do not knowingly collect personal information from children. If you believe a child has provided us information, contact us and we will delete it.
12. Third party websites
This site links to websites we do not operate, including sellers and payment processors. Their privacy practices are their own, and we encourage you to read their policies before submitting information or completing a purchase.
13. Changes to this policy
We may update this policy as the site or the law changes. Updates are posted here with a new date at the top and take effect when posted. Material changes will be highlighted on this page. Please review it periodically.
