Privacy Policy

Last updated October 5, 2026

rootlet helps you find a baby name you love. It works fully without an account. This policy explains the data the app handles and why.

What we collect

• An anonymous identifier. When you connect with a partner or save your names, the app signs in and is given a random Firebase user id. It is not your name, email, or phone number.
• Your name choices. If you connect with a partner, the names you swipe — both liked and passed, with timestamps — are stored so the two of you can be matched. If you save your names to an email without a partner, the same swipes are stored with your account so a new phone can bring them back. If you do neither, your swipes stay only on your device.
• An email and password — only if you save your names. If you use “Save your names,” your email address and a password are stored so you can sign back in after reinstalling or switching phones. The password is stored in a form we can’t read. This is optional.
• Your last name — kept on your phone. Setup asks for a last name so first-and-middle combinations can be tried against it. It is saved in the app’s local storage on your device and is never sent to us or to anyone else — not even when you connect with a partner.
• Purchases — only if you buy rootlet Plus. A purchase goes through Apple. We receive a record of what was bought and when, so the app can tell whether Plus is active, and so a partner you have connected can share it. We never see your payment details.
• Anonymous usage counts — you can turn these off. The app records a few events about how it’s used: for example that setup was finished, how many names were swiped in a day, or that a partner connected. Each event carries only counts and simple settings, plus your phone model, system version, and the app version. They are tied to a random id created for this purpose, which is separate from your Firebase id and never linked to it. They never include the names you look at, like, or save, your last name, or your email.

How we use it

• To run the app: show names, sync your likes with your partner, and celebrate matches.
• To bring your names back after a reinstall or on a new phone, if you save them to an email.
• To understand how the app is used overall — such as how many names people swipe in a day — so we can improve it and decide which features to offer free.

We don’t sell your data, and we don’t use it for advertising.

Third parties

• Google Firebase (Authentication and Cloud Firestore) stores your anonymous id, your swipes, and your email and password. Google processes this data under its own terms; see Firebase’s privacy information.
• PostHog (product analytics) receives the anonymous usage counts described above and stores them in the United States. We’ve set it up not to look up your location or keep your IP address, and not to build a profile of you. See PostHog’s privacy policy.
• RevenueCat (purchases) processes rootlet Plus purchases and keeps the purchase history that lets you restore Plus on a new phone. It receives a random purchase id, your Apple ID’s purchase receipts, and, if you have connected a partner or saved your names, your anonymous Firebase id. It never sees your names. See RevenueCat’s privacy policy.
• Superwall (the Plus offer screen) shows the screen that offers rootlet Plus and decides which version of it you see. It receives a random id, your device model, system version, app version, and language, whether you have Plus, and a few non-identifying facts about how you use the app, such as whether you have connected a partner and who you are naming for. It never sees your names, your last name, or your email. See Superwall’s privacy policy.

We require these providers to protect your data to a standard equivalent to this policy.

Where it’s stored and for how long

Data on your device is kept in the app’s local storage. Cloud data is held in Google Firestore. We keep it until you delete it (see below) or it is no longer needed to provide the app. Anonymous usage counts are held by PostHog only for as long as they’re useful for spotting trends.

Your choices and deleting your data

• Use it with no account. The whole app works offline. Unless you connect a partner or save your names, the only thing that leaves your phone is the anonymous usage counts.
• Turn off usage counts at any time in Profile → Share anonymous usage stats. Nothing more is sent from then on, including anything still waiting to be sent.
• Disconnect from your partner at any time from Profile → Partner.
• Log out. Profile → Log out signs this phone out and clears it. Your saved names stay with your account until you sign back in or delete it.
• Delete your account and data. In the app, open Profile → Delete account to permanently remove your account, your email, and your swipes, and reset the app on your phone. (This removes your swipes; a connected partner keeps their own, and simply stops seeing your likes.) You can also email us at the address below. Usage counts aren’t tied to your account, so they can’t be found or removed this way; turning them off stops any more being collected.

Children

rootlet is intended for expecting parents and adults, not for children, and is not directed to children under 13. We do not knowingly collect personal data from children. Names you enter about your own children are provided by you, the adult user.

Changes

If this policy changes, we’ll update this page and the “last updated” date above.
