Last updated: 11 July 2026
Lights On ("the app", "we", "us") is developed and operated by Steve Frame ("the Developer"). This policy explains what information the app collects, how it is used, who it is shared with, and the choices and rights you have. Please read it carefully. By creating an account and using Lights On, you agree to the practices described here.
If you have any questions about this policy or your data, contact us at: privacy@lightson.love.
1. Who this policy applies to
This policy applies to all users of Lights On, worldwide. Because our users include people in the United Kingdom, the European Economic Area, and other regions, we aim to meet the standards of applicable data protection laws, including the UK GDPR and EU GDPR, regardless of where you live.
Lights On is intended for adults (18 and over) in a relationship who choose to share cycle-related information with a connected partner. It is not directed at children.
2. What Lights On does
Lights On helps couples by allowing one partner (the "cycle owner") to record information about their menstrual cycle and mood, and to choose what of that information is shared with their connected partner (the "supporting partner"). The supporting partner receives phase-appropriate guidance based on what the cycle owner has chosen to share.
The core principle of the app is that the cycle owner controls what is shared. Sharing is governed by in-app toggles that the cycle owner can change at any time, and either partner can disconnect at any time (see Section 6).
3. What information we collect
We collect only the information needed to provide the app's features:
Account information - Email address and password (used to create and secure your account).
Profile information you provide - Your name and your partner's name (as you enter them). - Your location, which may be a city or region you enter yourself, or an approximate location derived from your device's IP address to make suggestions relevant. We do not collect precise GPS location. You can edit or clear your location at any time.
Cycle and wellbeing information (health-related data) - Cycle start date and cycle length. - Daily or weekly mood signals you choose to set. - Optional symptom tags you choose to select. - Optional preferences you choose to share (for example, activities you enjoy, things you would prefer your partner not be prompted toward, and a free-text note).
Subscription information - Whether you hold an active subscription. Payments and subscription status are handled by RevenueCat and the app store; we do not collect or store your payment card details.
We do not collect analytics, advertising identifiers, tracking data, or behavioural profiles. We do not use third-party analytics or advertising SDKs.
4. How we use your information
We use your information solely to:
- Create and secure your account.
- Connect you with your partner via a pairing code.
- Store your cycle, mood, and preference information so the app can function.
- Share with your connected partner only the information you have chosen to share.
- Generate daily guidance for the supporting partner (see Section 5).
- Provide and manage subscriptions.
We do not sell your information. We do not use it for advertising. We do not use it for any purpose other than operating the app's features.
5. Third parties who process your data
Lights On relies on a small number of service providers to function. Each processes only what is necessary:
Supabase — hosts our database and handles account authentication and secure data storage. Your account and app data are stored on Supabase infrastructure. See Supabase's privacy practices at supabase.com.
RevenueCat — manages subscription status. RevenueCat receives a user identifier and subscription information, not your cycle or mood data. See revenuecat.com.
Anthropic (Claude API) — to generate the supporting partner's daily guidance, the app sends relevant context to Anthropic's Claude API. This may include the cycle owner's current cycle phase, mood signal, shared interests, shared preferences, and shared free-text note — but only where the cycle owner has enabled sharing. This data is sent to generate a single guidance message and is not used by us to build any profile. See anthropic.com for Anthropic's data handling practices.
Approximate location service — where you have not set your location manually, the app may use an IP-based lookup service to estimate your city or region. This uses your IP address to return an approximate location and is used only to make suggestions relevant.
We only share the minimum data necessary with these providers, and only to deliver the app's features.
6. What your partner can see, and disconnecting
When you connect with a partner, your partner can see only what you choose to share through the app's sharing toggles. Depending on your settings, this may include your current cycle phase, your mood signal, and the preferences you have chosen to share. If you turn a sharing setting off, that information stops being shared.
You can disconnect from a partner at any time. Disconnecting immediately and completely stops all sharing between you — your former partner can no longer see any of your information, and you can no longer see theirs. When you disconnect, your pairing code changes, so that reconnecting requires a new code to be shared. Both people keep their own accounts and data. This gives you direct control over ending a connection whenever you choose.
7. Data storage and security
Your data is stored securely using Supabase, with access controls that restrict data to you and — for the specific items you choose to share — your connected partner. We take reasonable technical measures to protect your information. However, no method of electronic storage or transmission is completely secure, and we cannot guarantee absolute security.
Data may be stored and processed on servers located outside your country, including in jurisdictions whose data protection laws may differ from your own. Where required, we rely on appropriate safeguards for such transfers.
8. Your rights and choices
You have the right to:
- Access the personal information we hold about you.
- Correct inaccurate information (much of which you can edit directly in the app).
- Delete your account and associated data (see Section 9).
- Withdraw sharing at any time using the app's sharing toggles, or disconnect from your partner entirely.
- Object to or restrict certain processing.
- Data portability, where applicable.
If you are in the UK or EEA, these rights are provided under the UK GDPR and EU GDPR. You also have the right to lodge a complaint with your local data protection authority.
To exercise any of these rights, contact us at privacy@lightson.love.
9. Deleting your account and data
You may delete your account and associated personal data at any time, directly within the app, from the settings on your profile screen. Deletion is permanent and removes your profile, cycle, mood, and preference data. If you are connected to a partner at the time, that connection is ended as part of deletion.
If you prefer, you may also request deletion by emailing us at privacy@lightson.love from the address associated with your account, with the subject line "Delete my account." We will action the request within 30 days and confirm once done.
Information you previously shared with a connected partner while your account was active may remain visible to that partner unless they also delete their data or you disconnect before deleting.
10. Data retention
We retain your information for as long as your account is active. When you delete your account, we delete your associated personal data as described in Section 9. Subscription records may be retained by RevenueCat and the app store as required for their own legal and financial obligations.
11. Children
Lights On is not intended for anyone under 18, and we do not knowingly collect information from children. If you believe a child has provided us information, contact us and we will delete it.
12. Changes to this policy
We may update this policy from time to time. When we do, we will revise the "Last updated" date at the top. Significant changes may be communicated in-app. Your continued use of the app after changes take effect constitutes acceptance of the updated policy.
