Your information stays yours

Privacy Policy

Last updated: 16 October 2026

Lights On is developed and operated by Steve Frame. This policy explains what information Lights On collects, why it is processed, how it is shared and kept, and the choices available to you.

Lights On is built on one principle: your personal and cycle-related information belongs to you, and you control what is shared with your connected partner.

Private journal entries and ratings are never shared with your partner and are never sent to third-party AI services.

1. Who this policy applies to

This policy applies to Lights On users worldwide, on Google Play and the Apple App Store. We aim to follow applicable privacy laws, including the UK GDPR and EU GDPR where they apply. Lights On is intended only for adults aged 18 and over.

2. What Lights On does

Lights On is a relationship-support app. One partner, the cycle owner, can set up their cycle information, share a daily signal and keep private reflections. Their connected supporting partner receives one practical suggested action, only after the cycle owner has approved it. The cycle owner controls what is shared and can change those settings, or disconnect, at any time.

3. Information we collect

Account and profile information

• Email address and sign-in details
• Internal account identifiers
• Your name, and the name your connected partner enters for their own account
• Your role in the app (cycle owner or supporting partner) and, if you choose to give it, how you identify
• Your device's time zone, which we use to decide when your day starts
• A city or region, only if you choose to type one in (optional)
• A device notification token, if you allow notifications

Cycle and wellbeing information

• Cycle set-up details: cycle status (for example regular, irregular, hormonal contraception, perimenopause or menopause), cycle start date, cycle length and period duration
• Your current or calculated cycle phase, and any manual adjustment you make to it
• Daily mood or support signals, and optional daily notes (“Words for the day”)
• Optional daily symptom or wellbeing check-ins
• For a supporting partner: optional context they select about the person they support, such as an age range

Actions and outcomes

• The practical actions suggested to a partner, whether the cycle owner approved them, and whether and how they were completed or logged

Private journal entries and ratings

Private journal entries are strictly private to their author. They are never shared with a partner and never sent to third-party AI services.

Pairing and subscription information

• Pairing codes, paired account records, sharing settings and connection status
• Subscription product, entitlement, status, expiry and app-store purchase status. Payments are processed by Google Play or the Apple App Store; we do not receive your payment card details.

Technical information

• Basic product events, such as which screens are used, recorded in our own database to keep the app working and improve it
• Like most online services, our hosting and service providers receive technical information such as your network address when your device connects. We do not use it to work out where you are.

Lights On does not use advertising SDKs, does not use analytics SDKs to build advertising profiles, and does not sell behavioural profiles.

4. Why and how we use information

• Create and secure accounts
• Connect partners
• Record cycle, signal and mood information
• Apply your sharing settings
• Share permitted information with a connected partner
• Suggest practical actions. Most come from a library of suggestions written by us; AI-assisted guidance is used only if you have opted in (see section 8)
• Store private journal entries and ratings
• Manage subscriptions
• Keep the service secure and prevent misuse
• Respond to privacy and support requests

We do not sell personal, cycle or health-related information, and we do not use it for targeted advertising.

5. Legal basis and consent

Where applicable, essential account and service information is processed to provide the service. Cycle and wellbeing information is health-related information and is processed with your explicit consent where required.

Lights On uses a separate in-app AI-consent step before relevant personal information is sent to Anthropic's Claude API. If consent is not given, that information is not sent for AI-generated guidance. You can withdraw consent at any time in the app or by contacting privacy@lightson.love.

6. What your partner can see

A connected partner sees only what your sharing settings allow. Depending on your settings, this can include:

• Your current cycle phase, for cycle owners who track a regular cycle
• Your daily mood signal
• A daily note you deliberately choose to share
• Practical actions based on the context you have chosen to share, after you have approved them

Sharing of your cycle phase and mood signal is switched on when you finish setting up. You can switch either one off at any time in your Dashboard. Only the cycle owner can change sharing settings.

Private journal entries, private notes and signals you have not shared remain private.

7. Disconnecting

Either person can disconnect at any time. Sharing stops immediately, the pairing ends, and each person keeps their own account and private data unless they choose to delete it.

8. AI-assisted guidance

Most guidance in Lights On comes from a library of suggestions written by us and does not involve AI. AI-assisted guidance is being introduced gradually.

AI-assisted guidance is generated only if you have given AI consent in the app. You can withdraw consent at any time by switching off AI-Generated Daily Guidance in your settings or by contacting privacy@lightson.love.

Where it is switched on, we send Anthropic (the Claude API) the minimum relevant context. This may include your cycle phase, a mood signal you have shared, a daily note you deliberately shared, and an approximate city or region if you entered one. Private journal entries and ratings are never sent to Anthropic. API data is not used to train AI models.

9. Health and cycle information

Cycle, phase and mood information is health-related information. We treat it as sensitive. We process it only with your consent, store it against your account, and never sell it or use it for advertising. It is not given to RevenueCat, and your partner sees it only through the sharing settings you control.

10. Location

Lights On does not access your device's location and does not track your movements. If you choose to enter a city or region, we store it against your account and use it only to suggest nearby places in the app. Entering a location is optional, and you can change or remove it at any time.

11. Service providers

Supabase

Database infrastructure, authentication and secure data storage.

RevenueCat

Subscription and entitlement management. Cycle notes, mood information and private journal content are not provided to RevenueCat.

Google Play and the Apple App Store

Distribution of the app and processing of subscription payments. We receive your purchase status, not your payment card details.

Push notification services

Apple, Google and Expo deliver notifications to your device using a device notification token.

Anthropic (Claude API)

Used only for AI-assisted guidance, and only after you have given AI consent. See section 8 for what may be sent and what is never sent.

Google Maps

If you tap “Find somewhere nearby”, the app opens Google Maps in your browser with the type of place and the city or region you entered. This happens only when you tap it. Google handles that search under its own privacy policy.

12. International transfers

Some providers may process information outside your country. Where required, appropriate transfer mechanisms and contractual safeguards are used.

13. Data storage and security

Lights On uses access controls and Row Level Security intended to isolate each user's data and limit partner access to information you have chosen to share. No electronic system can be guaranteed absolutely secure.

14. Your rights

• Access or correct your information
• Delete your information
• Withdraw consent
• Restrict or object to certain processing
• Request portable information
• Complain to an appropriate authority

Contact privacy@lightson.love to exercise a privacy right.

15. Account deletion

You can permanently delete your account in the app. You can also email privacy@lightson.love from your account email with the subject “Delete my account”. We aim to action verified requests within 30 days. Deleting your account does not delete your partner's account; the connection between you ends.

16. Data retention

Information is retained only as long as reasonably necessary to provide Lights On, comply with legal obligations and protect the service. Account information is permanently deleted when you delete your account.

17. Guidance and medical disclaimer

The suggestions in Lights On, whether from our library or AI-assisted, are informational and supportive. They do not diagnose a condition, determine how someone definitely feels, replace direct communication, or replace professional medical or mental-health advice.

Lights On is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Always consult a qualified healthcare professional for any medical concerns.

18. Children

Lights On is intended only for adults aged 18 and over.

19. Policy changes

We may update this policy and will revise the “Last updated” date. We will give additional notice or ask for fresh consent where required, including when AI-assisted guidance is introduced.

20. Complaints

Contact us first so we can address your concern. You may also complain to the UK Information Commissioner's Office or your competent EU/EEA data-protection authority.
