Privacy policy

Lettza is operated by Ellul Solutions Ltd. The controller of the personal data on this site is Ellul Solutions Ltd, company 17364530, registered in England and Wales (Companies House), 14 Warfield Crescent, Waterlooville, England, PO7 7JP. This page explains what happens to information submitted on this site. It was last changed on 2026-11-08.

What we collect and why

When you use a worksheet on this site nothing you type leaves your browser: the arithmetic runs on the page and we never see the rent, the tenant or the address. If you send an enquiry we collect the name, email, business and message you put in the form. If you open an account we collect your email and the records you choose to keep in it: your properties, units, leases, tenants, rent lines, work orders and documents. We deliberately collect no credit, criminal or screening data about any tenant, because Lettza does not do screening.

Legal basis and sharing

We do not sell your details and we never pass an enquiry to a letting agent, a management company or a lead broker. We share data only with the processors that make the service work: Cloudflare (hosting and the database), Stripe (payment, which handles your card details directly so we never hold them), and Mailgun (the emails the service sends). Each acts on our instructions under a contract, and we name them so you can read their terms yourself.

Retention

Enquiry records are kept for 24 months from when they are sent, then deleted, and any copy held to pass an enquiry to a firm has the name, email, phone and message removed at the same point. Aggregate statistics that identify nobody are kept indefinitely.

Email updates and results

Email updates: If you sign up for updates from this site (the box at the foot of a page, or the tick on an enquiry form), we store your email address, the exact sentence you agreed to and its version, where you signed up and when. We email you only about what that sentence names. A sign-up from the box starts only once you confirm it from the email we send you; ticking the box on an enquiry you send is your consent and needs no second step. The lawful basis is your consent, and every email carries a one-click unsubscribe.

Emailing you a result: If you ask us to email you a result from a calculator or a checker, we send it to you once. Your address is not added to any list unless you also tick the separate box to get updates.

Email updates: kept while you are subscribed. A sign-up never confirmed is deleted after 30 days. After you unsubscribe, the record of your consent and of the emails sent to you is kept for 24 months as evidence, then deleted. We keep a one-way hash of an address that unsubscribed, bounced or complained, so it is never emailed again.

Analytics

This site uses cookieless, aggregate analytics. No advertising cookies, no cross-site tracking, no consent banner needed.

Your rights

You can ask what we hold about you, ask for a copy, or ask for deletion at any time: hello@lettza.com. We respond within one month. You can complain to the Information Commissioner's Office (ico.org.uk) in the UK. Ellul Solutions Ltd's establishment in the EU is in Malta, so its lead supervisory authority in the EU is the Office of the Information and Data Protection Commissioner (idpc.org.mt); you can also complain to the authority in the EU country where you live or work.
