Privacy Policy
Last updated: 26 June 2026
This notice explains how we collect, use, share and protect your personal data when you request a quote or book a clean with DepositBack. We are committed to handling your information lawfully and transparently under the UK GDPR and the Data Protection Act 2018.
1. Who we are
DepositBack is a trading name of Helix AI Group Ltd, a company registered in England and Wales (company number 16454835). We are the "data controller" responsible for your personal data.
If you have any questions about this policy or wish to exercise your rights, contact us at: hello@depositbacklondon.com.
2. The personal data we collect
| Category | Examples |
|---|---|
| Booking details | Your name, the property address and postcode, property size and selected add-ons, your chosen date and time slot, and any notes you provide (e.g. access or parking information). |
| Contact details | Your phone number and, optionally, your email address. |
| Payment information | Card payments are processed securely by Stripe. We do not see or store your full card number — we receive only confirmation of payment and limited details (e.g. amount, status). |
| Technical & usage data | Information collected automatically when you use the site, such as your device/browser type, pages viewed, and interactions — via cookies and similar technologies (see section 7). |
3. How and why we use your data (lawful bases)
| Purpose | Lawful basis |
|---|---|
| To provide your quote, take payment, and carry out your clean | Performance of a contract with you |
| To contact you about your booking (including calling you if a payment is started but not completed) | Performance of a contract / our legitimate interests in recovering and confirming bookings |
| To honour our re-clean guarantee and handle complaints | Performance of a contract / legitimate interests |
| To keep records and meet legal, tax and accounting obligations | Legal obligation |
| To measure and improve our website and advertising (analytics, session insights, conversion tracking) | Your consent (where required) and/or our legitimate interests |
4. Who we share your data with
We do not sell your personal data. We share it only with trusted parties who help us run the service:
- Our cleaning teams / operatives — they receive the details needed to carry out your clean (e.g. name, address, access notes, date and time).
- Stripe — our payment processor, to take and manage card payments securely.
- FormSubmit — the service that delivers your booking details to us by email.
- Google (Google Ads conversion tracking) and Microsoft (Clarity analytics) — to understand site usage and advertising performance.
- Professional advisers and authorities — e.g. accountants, or where required by law.
5. International transfers
Some of our providers (such as Stripe, Google and Microsoft) may process data outside the UK. Where they do, we rely on appropriate safeguards — such as UK adequacy regulations or the International Data Transfer Agreement / Addendum — to ensure your data remains protected.
6. How long we keep your data
We keep your booking and payment records for as long as needed to provide the service and to meet our legal, tax and accounting obligations (generally up to 6 years for financial records). Analytics data is retained according to each provider's standard retention periods. We delete or anonymise data when it is no longer needed.
7. Cookies and analytics
Our site uses cookies and similar technologies for essential functionality and for analytics/advertising measurement (Google Ads and Microsoft Clarity). These help us see how visitors use the site and how well our advertising performs. You can control or disable cookies through your browser settings.
8. Your rights
Under UK data protection law you have the right to: access your data; have inaccurate data corrected; have your data erased; restrict or object to processing; data portability; and to withdraw consent at any time. To exercise any of these, contact us using the details in section 1.
You also have the right to complain to the Information Commissioner's Office (ICO) — ico.org.uk, helpline 0303 123 1113 — though we'd appreciate the chance to address your concern first.
9. Changes to this policy
We may update this policy from time to time. The "last updated" date at the top shows when it was last revised.
