Wellness app privacy notice
Last updated 30 August 2026
This notice explains how Marlo Health Ltd collects and uses personal information when you use the Marlo Wellness Score, dashboard and check-in services. It sits alongside the privacy information for purchases made through the Marlo online store.
Who we are
Marlo Health Ltd is the controller of personal information used by this app. We are registered in England and Wales under company number 17145430. Our registered address is 128 City Road, London, EC1V 2NX. You can contact us at hello@marlohealth.com.
Information we collect
- Your email address, name, account identifiers and sign-in information
- Your dog’s profile, including name, breed, age, weight and photo
- Wellness answers, scores, check-ins and progress over time
- Shop account connection and MD1 subscription status
- Email choices, cookie choices and records of when those choices were made
- Feedback you send us and whether you allow us to contact you
- Technical information such as device, browser, pages visited and referral source
Information about a dog is not usually personal information by itself. It becomes part of your personal information when it is connected with your account or email address.
How we use information
- To calculate and show your dog’s wellness results
- To save your account, history and check-ins
- To send requested results and essential account messages
- To send reminders, wellness guidance and offers according to your choices
- To connect an eligible MD1 subscription and operate the 90 day challenge
- To keep the service secure, understand performance and improve the app
- To respond to feedback, support requests and legal obligations
Our legal bases
We use information where it is needed to provide the service you request, where you have given consent, where we have a legitimate interest in running and improving Marlo, and where the law requires us to do so. You can withdraw marketing and optional analytics choices at any time.
Who we use to provide the app
We use trusted providers to operate Marlo, including the following.
- Supabase for accounts, database and private image storage
- Vercel for application hosting and delivery
- Klaviyo for requested and marketing emails and consented onsite activity
- PostHog for product analytics and consented session replay; replay masks page and input text and does not collect network bodies, headers or console output
- NeverBounce for email address validation
- Shopify for Shop identity, purchases and subscription management
- Google, Meta and TikTok for measurement where optional cookie consent allows it
Some providers process information outside the United Kingdom. Where that happens, we use the contractual and legal safeguards required for the transfer.
How long we keep information
An unclaimed guest snapshot is normally available for seven days. Account information, dog profiles and wellness history are kept while your account remains active or until you delete them. We keep consent and suppression records where needed to respect your choices and demonstrate them. Store orders may be retained separately where needed for tax, accounting, consumer protection or legal claims.
If you tell us that your dog has died or is no longer in your care, we stop dog-specific messages and keep the history in your account until you reactivate or delete it.
Your choices and rights
You can update email and dog preferences in Settings. You can also download your app data or delete your account from the Your data page.
Depending on the circumstances, you can ask us for access, correction, deletion, restriction, portability or an objection to how we use your information. You can withdraw consent at any time. Contact hello@marlohealth.com to make a request.
You can complain to the UK Information Commissioner’s Office at ico.org.uk if you are unhappy with how we use your information. We would appreciate the chance to help first.
Changes to this notice
We may update this notice as the app develops. We will change the date above and explain material changes in the app or by email where appropriate.
