1. What stays on this iPhone or iPad
Fia keeps what you log in a database on this iPhone or iPad, under iOS’s complete file protection: while the device is locked, the database can’t be read. That includes:
- Periods, flow, symptoms, mood, energy, leaks, and how your body feels
- Pelvic-floor sessions, the journey, and routines you build
- Journal entries and notes
- Your name, your stage, and details such as your contraception
A few things live outside that database. Settings, and a pregnancy due date, are in the app’s preferences. The app lock and Discreet Mode settings are in the device’s Keychain. Widgets read a small summary, the cycle day and phase, the forecast, and today’s check-in, from a container they share with the app. These use iOS’s standard protection, which keeps them encrypted until you first unlock the device after it starts, so widgets can show the day while it’s locked.
2. Backups
Your device’s backups, to iCloud or to a computer, include Fia’s database unless you turn on Privacy → Keep out of iCloud Backup. Settings kept outside the database, the widgets’ summary, and the names Fia uses in partner notifications are always in a backup. What partners share with you never is. Periods Fia brings in from Apple Health are never in a backup, whatever this is set to. On a new device, bring them in again in Settings → Apple Health.
Apple encrypts iCloud Backup; with Advanced Data Protection on, only your devices can read it. A backup on a computer is encrypted only if you turn that on.
3. Optional iCloud sync
iCloud sync is off until you turn it on in Settings → iCloud sync. When it is on, what you log in Fia goes to your own private iCloud container, iCloud.com.sideswipelabs.fia, through Apple’s CloudKit, in encrypted fields. Apple encrypts it; with Advanced Data Protection on, only your devices can read it. We cannot. Nothing from Apple Health goes: periods Fia brings in from Health stay in a separate store on this device that sync never reads.
Turning sync off stops syncing, and leaves the copy already in your iCloud. Section 13 says how to remove it.
4. Partner sharing
Partner sharing is off until you turn it on, and sharing your own cycle is for adults, 18 and over. You can invite up to five people. Each person has their own choices, and sees what you share in Fia on their own iPhone.
What each person can see, as you choose:
- Your name and time zone, so their phone shows your day
- Your cycle day and phase, worked out four weeks ahead so their phone stays current
- A forecast of your next period, as a window
- A heads-up the day before your period, if you turn it on. It doesn’t say what for
- Your fertile window, only if you turn it on. It turns itself off after 90 days
- Check-ins you choose to send: your energy, up to five feelings, and a note if you write one
- Asks you send, such as a heat pack or a quiet night, with a note if you write one
The cycle day, forecast, and fertile window are worked out from the periods you log in Fia. Nothing Fia reads from Apple Health is shared: if the start of your current cycle came only from Apple Health, nothing of your cycle is shared until you add that period to Fia yourself. On hormonal contraception only the days you bleed are shared, and in pregnancy, after birth, and in menopause no cycle is shared.
They never see:
- Notes you log, or your journal
- Symptoms you don’t send in a check-in
- Sex, contraception, or tests you log
- Your practice
- Your history
- Data from Apple Health
How it travels. Each share is kept in your own iCloud, in an encrypted field, and shared with that person through Apple’s iCloud sharing. It never passes through SideSwipe Labs, and we cannot read it. iCloud keeps some details outside the encrypted field, such as when something changed, and shows each of you the name on the other’s Apple Account.
What comes back. The people you invite send back their name, their answers to your asks, and hearts for your check-ins, each with a few words if they write them. Your iPhone keeps asks, check-ins, and hearts for a week, and asks older than a week leave iCloud.
Safeguards. You invite each person with a one-time link. It lets in the first Apple Account that opens it, and closes after 7 days or once it’s used. Sharing starts as soon as your Fia sees that person join; until then, your shared space holds only your name. Your people shows the name on the Apple Account that joined. If someone else opens the link first, the person you meant finds it already used, and Fia asks them to tell you. You can then stop sharing with whoever joined in a tap, but what they saw before you stopped can’t be taken back. Making a link, sharing more, keeping the fertile window, and resuming ask for Face ID or Touch ID first. Sharing less never does. Every 90 days Fia asks whether you’re still happy sharing; nothing changes unless you change it.
Pausing and stopping. Pause, and nothing new is sent; they keep what they already have. Stop, and what you shared is deleted from iCloud, and their Fia forgets it the next time it opens. They aren’t told. Anything they already saved or screenshotted can’t be taken back.
Reporting. Each person’s sharing settings have Report something they sent, which opens an email draft to us. We can’t see what’s shared, so the email holds only what you write in it, and Fia’s version. Stopping or leaving ends what comes from that person at once.
If someone shares with you. You can follow up to five people. If you join someone still on an earlier version of Fia, your Fia also sends them a four-digit code, because that version asks for one. Your iPhone keeps their latest summary, their asks, and your answers, encrypted while your iPhone is locked and never in your backups, and forgets them when you leave or they stop sharing. If you leave, they see that you left.
5. The invite link
An invite link opens dearfia.com/invite. Links made by earlier versions of Fia open sideswipelabs.com/fia/invite, which works the same way. If Fia is installed, it usually opens Fia instead, and the page isn’t loaded. Your name, and the name you gave them, ride in the part of the link after the #, which a browser never sends to a server. The part before it holds the encoded iCloud link, which our web host receives with the page request, like any web address.
The page sends nothing anywhere, is not indexed by search engines, and sends no referrer. Its title and preview never show a name or a health word. The message Fia suggests with the link names you, and goes however you choose to send it.
6. Apple Health
Apple Health stays off until you connect it, in setup or in Settings → Apple Health, and Fia works without it. When you connect it, Fia can read your period history, ovulation test results, and sleep, and save your sessions as workouts (their type and time, with no calorie estimate), breathing sessions as mindful minutes, and the start and end of each period you log, never an estimate.
Once you’ve connected Apple Health, adding a contraception method asks Apple Health for permission to save it there. It saves nothing unless you allow it.
Periods you bring in from Apple Health are kept apart from the ones you log, in a store on this device that is never synced to iCloud, never in a backup, and never in what a partner sees. Ovulation tests and sleep are read when Fia needs them for your screens, and Fia doesn’t save them. All of it shapes your own forecast. A period you add to Fia yourself becomes one of your logs. Revoke access in the Health app or in iOS Settings, and Fia stops reading and writing. What Fia saved to Apple Health stays there until you delete it in the Health app or with Delete all data (section 13).
7. Notifications, widgets, and the Lock Screen
Fia’s reminders are made on this iPhone or iPad. Period reminders and phase notes are on once you allow notifications; the rest stay off until you turn them on. Private notifications make every reminder say only that you have one; they’re on from the start for 16- and 17-year-olds. Discreet Mode swaps the words: a period becomes a check-in, and phases become numbers.
Partner sharing uses Apple’s push service to tell the other phone that something arrived. Their Lock Screen says that an ask, a check-in, or a reply arrived, and may say who it’s from, never what it says. With Private notifications on, it says only that something is waiting.
Widgets and the Live Activity show what is on this iPhone or iPad. Lock Screen widgets show only the day, unless you turn on Cycle details at a glance. Home Screen widgets show your phase and when your period may start, to anyone who sees your Home Screen.
While a session runs, Handoff can offer it to your other Apple devices signed in to the same Apple Account. It carries the session’s name, and nothing you logged. If you use Siri or Shortcuts with Fia, Apple handles those requests; the actions that read or log your data don’t run while the app lock is on.
8. Network
No third party receives your data from Fia. Apple provides iCloud, the App Store, Apple Health, and notifications under its own privacy policy.
Fia’s own code makes no network requests. Its only traffic goes through Apple:
- App Store purchases and the rating prompt, through StoreKit
- Your own iCloud, if you turn on sync, and a check that you’re signed in to iCloud when you open Settings
- Your iCloud and theirs, and Apple’s push service, if you use partner sharing
Links you tap, such as this policy, a source, a help line, or the App Store, open in your browser or the app they belong to. Contact us, Report a problem with this exercise, and Report something they sent open an email draft to fia@sideswipelabs.com (earlier versions of Fia draft to hello@sideswipelabs.com, which reaches us too). The problem report adds the exercise’s name and Fia’s version, the partner report only Fia’s version, and nothing is sent unless you send it. If you save a share card, Fia asks to add it to your photo library; it can’t see your other photos.
If you turn on Share With App Developers in iOS Settings, Apple may share Fia’s crash reports with us. Apple controls that sharing, and a crash report describes where Fia failed, not what you logged.
9. Export
Privacy → Export my data makes a PDF or CSV on this iPhone or iPad, and Share a summary with your doctor makes a one-page PDF. They leave the device only through the share sheet, where you choose where they go. The PDF report carries your name as its author.
10. What we never do
- Receive your logs, your name, or anything you share
- Count your screens, taps, or sessions
- Ask for a Fia account, or use an advertising identifier
- Track you across other companies’ apps
- Sell or share personal information
11. Purchases
Fia Plus is sold through the App Store. Apple processes the payment. We do not see your card number, billing address, or Apple Account password, and Fia doesn’t link a purchase to anything you log. The price is set for each country and shown on the purchase sheet before you confirm. Monthly renews each month, Yearly each year, and Lifetime is one payment. Family Sharing is on. There is no free trial.
12. Children and teens
Fia is not directed at children under 13. When you set it up, it asks your age, from 16. For 16- and 17-year-olds, notifications are private from the start, and sharing your own cycle isn’t offered. There is no account, and Fia sends us nothing.
13. Deleting your data
- Delete all data, in Settings → Privacy, removes your cycles, sessions, journal entries, and settings from this iPhone or iPad, and from your iCloud if sync is on, or has been on, on this device. It ends all partner sharing, leaves everyone you follow, and clears Fia’s notifications.
- It also deletes what Fia saved to Apple Health, unless you turn that off in its dialog. A copy synced from another device whose sync was never on here stays: remove Fia’s data from iCloud in iOS Settings. Copies in earlier backups stay until those backups are replaced or deleted.
- It also clears Fia’s settings, the widgets’ summary, and the Siri suggestions made from what you did in Fia. Fia keeps what you log until you delete it.
- Partner sharing: stop sharing, with one person or everyone (section 4).
- The app: delete Fia, and what was only on this iPhone or iPad goes with it.
14. Your rights (GDPR & CCPA)
Fia sends us nothing from the app, so we hold no data about you from Fia: there is nothing for us to look up, correct, or delete. What you log is on your iPhone or iPad, in its backups, and in your own iCloud if you turn sync on, where you control it, as section 13 describes.
If you email us, we use your address and message only to reply, and delete the thread on request. EU/EEA users may lodge a complaint with their local data protection authority. California users: we do not sell or share personal information.
15. Changes
We will update this page and its version number when the policy changes.
Version 1.5, October 15, 2026: Fia’s own address, fia@sideswipelabs.com, is where to write about this policy and for support, and where Fia’s email drafts go. The studio’s address, hello@sideswipelabs.com, still reaches us.
Version 1.4, October 15, 2026: this policy, the terms and support move to dearfia.com, and invite links open dearfia.com/invite. An invite link lets in the first Apple Account that opens it, and sharing starts when that person joins, with no code to check. The people you invite send back no code, unless you’re still on an earlier version of Fia. Starting to share no longer asks for Face ID or Touch ID.
Version 1.3, October 13, 2026: periods from Apple Health stay on the device, out of iCloud sync, backups, and what partners see; workouts carry no calorie estimate; Delete all data can delete what Fia saved to Apple Health; each person’s sharing settings can report what they sent; and the app links this policy from Settings → Privacy and About.
Version 1.2, October 10, 2026: Fia has no analytics, and deletes the analytics consent and anonymous id that earlier test builds kept. Partner sharing reaches up to five people. This version also covers backups, the invite link, notifications and the Lock Screen, Handoff, and what Delete all data leaves.
