Privacy Policy

Last updated: 3 July 2026 · Version 2.0 · Covers the Genesyx website and the Genesyx: Fertility Tracker app

Genesyx Ltd ("we", "us", "our") respects your privacy and is committed to protecting your personal data. This policy explains how we collect, use and protect personal data when you visit genesyx.co.uk, join our mailing list, or use the Genesyx: Fertility Tracker mobile app.

The short version: on the website we collect your email address if you sign up for updates. In the app we collect your account email and the cycle and wellbeing information you choose to log. Your data is stored securely, never sold, never used for advertising, and you can permanently delete your app account and all of its data at any time — in the app or via our account deletion page.

1. Who we are

Genesyx Ltd
Company number: 16913651
Registered office: Unit 8 Axiom, Orbital Park, Ashford, TN24 0AA, United Kingdom
Email: info@genesyx.co.uk

For the purposes of UK data protection law, Genesyx Ltd is the data controller of the personal data described in this policy.

2. What we collect

Where	Category	Examples
Website	Mailing list data	Email address you submit to receive updates
Website	Technical data	IP address, browser type, device information, usage and cookie-related data where cookies are in use
App	Account data	Email address, display name, app preferences (such as theme)
App	Health & cycle data	Cycle settings and dates, daily logs and wellbeing entries you choose to record
App	Technical data	Basic device and app information needed to keep the service secure and working (for example, authentication tokens)

The app does not collect your precise location, contacts, photos, or advertising identifiers. It contains no advertising and no third-party analytics or tracking SDKs.

3. How we use it, and our lawful basis

Mailing list — to send you news about our launch, products and related updates. Lawful basis: your consent (UK GDPR Article 6(1)(a)). Unsubscribe at any time via the link in any email or by emailing us.
Providing the app — creating your account, syncing your logs between devices, and showing you your own information. Lawful basis: performance of a contract (Article 6(1)(b)).
Health and cycle data — this is special category data. We process it only with your explicit consent (Article 9(2)(a)), which you give when you choose to record it. You can withdraw consent at any time by deleting individual entries or your whole account.
Security and service operation — authentication, abuse prevention, and keeping the website and app working. Lawful basis: legitimate interests (Article 6(1)(f)).
Legal obligations — where we must comply with law or regulation (Article 6(1)(c)).

We do not use your data for advertising, sell personal data, or make automated decisions with legal effects about you.

4. Where your data is stored

App data is stored in our database hosted by Supabase and protected by row-level security, so your records are only accessible to your own authenticated account. All data is encrypted in transit using TLS and encrypted at rest by our hosting providers.

5. Who we share it with

We share personal data only with the service providers (processors) needed to operate Genesyx:

Supabase — app database hosting and authentication.
Shopify — website hosting and storage of website form submissions.
Klaviyo — mailing list management and update emails.
Our transactional email provider — solely to send app account emails such as sign-up confirmation and password resets.
Professional advisers, regulators or authorities where required by law.

These providers process data on our instructions under data processing agreements. We do not share your data with advertisers or data brokers, and we will never disclose your health data to anyone except where the law requires it.

6. International transfers

Some of our service providers may process or store personal data outside the UK. Where that happens, we take reasonable steps to ensure appropriate safeguards are in place, such as UK-approved contractual clauses.

7. How long we keep it

Mailing list: until you unsubscribe, ask us to delete it, or we close the list.
App data: for as long as your account exists. When you delete your account, your profile, cycle settings, daily logs and authentication record are permanently deleted immediately. Residual copies in encrypted backups expire on our providers' standard rotation and are not used for any other purpose.

8. Deleting your app account and data

You can permanently delete your app account and all associated data at any time, in two ways:

In the app: Profile → Delete account. Deletion is immediate and cannot be undone.

Without the app: follow the steps on our account deletion page.

9. Your rights

Under UK data protection law, you have the right to:

access a copy of your personal data;
correct inaccurate or incomplete data;
delete your data ("right to erasure");
receive your data in a portable format;
withdraw consent at any time for data processed on the basis of consent;
object to or restrict certain processing;
complain to the UK Information Commissioner's Office (ICO) at ico.org.uk.

To exercise any of these rights, email info@genesyx.co.uk. We will respond within one month.

10. Children

The website and app are intended for adults and are not directed at anyone under 18. We do not knowingly collect personal data from children. If you believe a child has provided us with data, contact us and we will delete it.

11. Not medical advice

Genesyx provides educational wellness information and personal tracking tools. It is not a medical device and does not provide medical advice, diagnosis or treatment, and it should not be used as a form of contraception. Always speak to a qualified healthcare professional about your fertility and health.

12. Data security

We take appropriate technical and organisational measures to protect personal data from unauthorised access, loss, misuse, alteration or disclosure.

13. Changes to this policy

We may update this policy from time to time. Material changes will be posted on this page with a revised "Last updated" date, and app users will be notified in the app before changes take effect.
