Privacy Policy
WifeLine is a cycle, mood and pregnancy tracker for one person and a partner dashboard for the other. What you log is personal, so this page says plainly what we collect, who can see it, and how to remove it.
The short version. Your entries are shared with one person: the partner you link. We don't show ads, run third-party analytics or sell your data. Intimacy entries can only be read by the person who logged them. Deleting your account in the app deletes your data.
What we collect
Your account
Your name and the email address or phone number you sign in with. If you use Google sign-in, we receive your name and email from Google. Passwords are handled by Firebase Authentication; we never see them.
Your profile and settings
Whether you joined as her or him, who you're linked with, your cycle settings (such as average cycle and period length), any optional "about me" and gift preferences you fill in, and app settings like theme, home layout, notification choices, time zone and reminder time.
What you log
- Cycle and daily logs: period dates and flow, moods, symptoms, energy, notes, how connected you feel, what you'd like to talk about, and any optional entries you choose to track, such as sleep, exercise, water, weight, basal body temperature, cervical signs, ovulation and pregnancy tests, and intimacy.
- Pregnancy and baby: due date, pregnancy logs, contraction sessions, your baby's name and birth date, and feedings.
- Things the two of you share: notes, daily check-ins and moves, Read the Room guesses, favors in the Jar, special days and events, date ideas, gift ideas, wishlist items, the shopping list and journal entries.
From your device
- A push notification token, so we can send the reminders and partner alerts you've turned on.
- Crash reports when something breaks: the error message and technical details, the screen you were on, the app version, the platform and a browser or device description. They're linked to your account so we can fix the problem, and used for nothing else.
What we don't collect
No location, no contacts, no advertising identifiers and no third-party analytics. Your app PIN never leaves your device: only a salted hash is stored on the phone itself, and fingerprint or face unlock is handled by your phone's operating system. When you scan a partner's code, the camera image is read on your device and never uploaded.
How we use it
To run WifeLine: syncing between you and your partner, predicting periods, fertile windows and phases, showing insights, sending the notifications you've asked for, and powering features like the Line and the Jar. To keep it working, we read crash reports. If you write to us, we use your message to reply.
We don't use your information for advertising, we don't sell it, and we don't share it with data brokers.
Who can see it
You and your partner
Once you link with a partner using a code, they can see what the app shows a partner: things like the cycle, phase, daily logs, notes, events and the Jar. Some things never reach them:
- Intimacy entries are stored in a separate record that only the person who logged them can read. Our database rules enforce this.
- Gift ideas are private to the person who saved them.
- A date idea marked as a surprise stays hidden from your partner until you reveal it.
- She can turn off sharing her insights with him at any time in Settings.
Either of you can unlink, which ends your partner's access.
The services that run WifeLine
We use a few providers to host and deliver the app. They process data on our behalf to provide their service:
- Google Firebase for sign-in, the database, server functions and push notifications.
- Apple and Google push services, which deliver notifications to your device.
- Cloudflare, which hosts this website and the web app.
- Google Fonts, which serves the typefaces (your browser requests them from Google).
- GitHub, which hosts Android app updates when you download one.
When the law requires it
We'll disclose information only if we're legally required to, and we'll push back on requests that aren't valid.
Your choices
- Unlink from your partner in Settings › Partner.
- Share less: turn off sharing insights, and choose which notifications you get. Discreet notifications keep cycle and pregnancy details off your lock screen.
- Lock the app with a PIN, and fingerprint or face unlock where your phone supports it.
- Delete your account in Settings › Privacy & security. This removes your account and sign-in, your profile, cycles, daily and private logs, pregnancies, contractions, journal, check-ins, feedings, gift ideas, wishlist, notes you sent or received, favors, partner codes and crash reports. Events and date ideas you created are deleted; ones your partner created stay with them, without you.
How long we keep it
For as long as your account is open. When you delete your account, your data is removed from our database.
Security
Every record is locked by database rules to its owner and, where it's meant to be shared, their linked partner. Data is encrypted in transit, and our database provider encrypts it at rest. No system is perfectly secure, but we treat what you log as the sensitive information it is.
Health information
WifeLine is a personal tracker, not a healthcare provider or a medical device, and it isn't a form of contraception. See the terms for more.
Children
WifeLine is meant for adults. It isn't directed at children, and we don't knowingly collect information from anyone under 13.
Changes
If this policy changes, we'll update the date at the top of this page. For significant changes, we'll also let you know in the app.
