Privacy Policy
Last updated: November 13, 2026
1. Who we are
PlugPayback (plugpayback.com) is an independent tool site about plug-in solar, operated by Upcloud Lda (NIF PT514564016). In this policy, "we", "us" and "our" refer to Upcloud Lda.
2. What information we collect
The calculator
We store nothing you type. Your answers stay in the page and in the link you can copy or share. We keep no database of results. A shared link holds only the answers and a coarse location (the first digits of a postcode, or a US state), never an address.
Analytics data
We use Umami Analytics, a privacy-friendly, cookie-free analytics tool that we run ourselves, to understand how visitors use the site. Umami collects:
- Pages visited. The page address can include your calculator answers, with only the first digits of your postcode or your state.
- Referring website
- Browser, operating system, device type, screen size and browser language
- Country, region and city of the visit (derived from your IP address, which is not stored)
- Whether you ran a calculation, shared a result, or clicked a product link or the main button
Umami does not use cookies, does not track you across websites and does not store personally identifiable information. Your IP address is never stored or logged by it. It honours your browser's Do Not Track setting. To keep a browser out of the statistics altogether, open any page once with ?notrack=1 added to the address.
Choosing your country
To show the right country, currency and rules, the page reads the country and region that our hosting provider derives from your IP address. We use it for that page view only and do not store it.
No other personal data collection
We do not run advertising, contact forms, user accounts, newsletters or comment systems. We do not directly collect your name, email address or any other personal data. If you email us, we use your address and message only to answer you.
3. Cookies
This website sets no cookies of its own and shows no cookie banner, because there is nothing to consent to. See our Cookie Policy for what is kept in your browser and what happens when you follow a link to a shop.
4. Legal basis for processing (EU/EEA visitors)
For visitors in the European Economic Area, the legal basis is our legitimate interests (Art. 6(1)(f) GDPR): understanding how the site is used through anonymised, cookie-free analytics, showing the right country, and answering messages you send us.
5. Third-party services
- Cloudflare: hosts and delivers this website. Like any host, it processes your IP address to send you the pages. Cloudflare's privacy policy applies: cloudflare.com/privacypolicy.
- Umami Analytics: our own installation, hosted with Vercel. No cross-site tracking, no cookies, no personal data stored.
- Shops and affiliate networks: product links lead to the shop's own website, where that shop's privacy policy applies. Links marked "affiliate" pass through an affiliate network such as Awin, which may set a tracking cookie on its own domain (not ours) to attribute a purchase. We may earn a commission at no extra cost to you. Awin's privacy policy: awin.com/gb/legal/privacy-policy.
Fonts, images and scripts are served from our own domain, apart from the analytics script.
6. Data retention
We do not store personal data ourselves. Anonymised analytics data (page views, referrers, actions) is kept for up to 24 months to understand usage trends. Emails you send us are kept only as long as needed to deal with your message.
7. Your rights
If you are in the EEA, you have the right to access, rectify, erase, restrict or object to the processing of your personal data, and the right to data portability. You can also complain to a data protection authority; ours is the CNPD in Portugal. For questions about our data practices, contact us at info@plugpayback.com.
8. Changes to this policy
We may update this privacy policy from time to time. Changes are reflected by the "Last updated" date at the top of this page.
