Privacy policy

1. Who we are

Count Split is an app made by Rayslight ("we", "us"). This policy explains what information Count Split handles, why, and the choices you have. It applies to the Count Split app and to countsplit.rayslight.com.

2. What stays on your phone

Count Split is built to work offline. Everything you enter is saved on your phone first:

• Your groups: their names, emoji, descriptions, currency, and the names of the people you add.
• Your expenses: titles, amounts, dates, categories, who paid and how each one is split, and any photos you attach.
• Your settings: language, theme and colors, your public nickname, and app lock settings.

If you turn on app lock, your PIN, pattern or password stays on your phone. Fingerprint and face unlock are handled by your phone's system; Count Split never receives your fingerprint or face data.

If you don't sign in, this information doesn't leave your phone unless you share a group or export a backup yourself.

3. If you sign in

Signing in is optional. It lets you back up your groups, use them on another device and share them with friends. You can sign in with Google, Apple (on iPhone) or an email address and password.

What we receive

• Your name, email address and a unique account ID.
• Your profile photo, if your Google or Apple account has one.
• Which sign-in method you used.

If you use an email and password, your password goes to our sign-in provider (Firebase Authentication) and is never visible to us. We use your email address to send the link that confirms it when you create an account, and a reset link if you forget your password. We don't send marketing email.

What syncs to the cloud

While you're signed in, Count Split keeps a copy of your profile (name, public nickname, email, photo link and preferences) and of your groups and expenses in the cloud, so you can restore them on a new phone. Changes you make offline sync when you're back online.

4. Shared groups

When you share a group, the group and its expenses (including attached photos), the names of its members, the account IDs of members who joined, and the group's roles and settings are stored in the cloud so every member sees the same numbers.

• Anyone who has the invite link or QR code can view the group. Share it only with the people in the group.
• Members who join can see the group and, depending on the group's settings, add expenses, share it or edit it.
• If a group asks for approval, your request to join includes your name and email address so the group's owner and admins can recognise you.
• Names you type for other people are visible to everyone in that group. Please add people only with their permission.

5. Phone permissions

• Camera: only when you scan a group's QR code or take a photo of a receipt.
• Photos and media: only when you attach a picture to an expense or save an image or backup you export.
• Fingerprint or face unlock: only if you turn it on for app lock.
• Internet and network state: to sync, and to know when you're back online.

Count Split does not use your location, contacts or microphone.

6. What we don't do

• We don't show ads, and the app contains no advertising or analytics trackers.
• We don't sell or rent your information, or share it for advertising.
• We don't read your groups or expenses except when you ask us for help and give us permission.

7. Service providers

We use a small number of providers to run Count Split. They process data only to provide their service to us:

• Google Firebase (Google LLC): sign-in (Firebase Authentication), cloud storage of synced and shared data (Cloud Firestore, stored in Google's European multi-region), and hosting of this website. See Firebase privacy and security.
• Google Sign-In and Sign in with Apple, if you choose them to sign in.
• Google Play, which delivers the app and its updates.

Because these providers operate worldwide, your information may be processed in countries other than your own. They protect it under their own security commitments and the agreements we accept when using them.

We may share information if the law requires it, or to protect the safety, rights or property of our users, the public or Rayslight.

8. How long we keep data

• Data on your phone stays until you delete it in the app or uninstall Count Split.
• Cloud data stays while your account exists. When you delete your account, we delete your account, your profile and your synced copy of your groups.
• A shared group belongs to all of its members, so it stays available to them after you leave or delete your account. If you own a group, you can delete it for everyone first.
• A group deleted by its owner is removed from the cloud for every member.

9. Your choices and rights

• Use it without an account. Nothing syncs until you sign in.
• See, correct or export your data: your groups and profile are in the app, and Profile → Data management lets you back up and export them.
• Delete a group: from the group's menu. Owners delete it for everyone; others remove it for themselves.
• Delete your account: in the app under Profile → Delete account, or see how to delete your account.
• Ask us: you can ask for a copy of the information we hold about you, or ask us to correct or delete it, by writing to hello@rayslight.com. We reply within 30 days.

Depending on where you live, you may have further rights under data protection law, including the right to object to or restrict processing and to complain to a data protection authority.

10. Security

Data travels between the app and the cloud over encrypted connections and is encrypted at rest by Google. Access rules on our database let only a group's members change it, following the roles its owner sets, and only you can read your own profile. App lock adds a layer on your phone. No system is perfectly secure, so please keep your phone locked and your password private.

11. Children

Count Split is not directed at children under 13, and we don't knowingly collect their information. If you believe a child has given us information, contact us and we'll delete it.

12. Changes to this policy

If we change this policy, we'll update the date at the top. If a change is significant, we'll also tell you in the app before it applies.
