Sharing Your Cycle & Health Data With a Partner: A Guide to Every App's Privacy Controls

How We Picked These Apps

We compared the partner-sharing features built into the period and cycle apps people actually use, plus Apple's general Health app sharing, since a lot of people ask about that too. For each one, we verified what data is shared, who controls it, and how to revoke access directly from the app's current support documentation and privacy policy rather than its marketing pages, checked in August 2026. Partner-sharing features change often, so treat the specifics here as a snapshot and confirm the current setup in-app before you rely on it.

Full disclosure: this site is published by Holland Neurotech Inc., the maker of Go Go Gaia. The list isn't ranked by preference. Each option is presented for the situation it fits, and we've put Go Go Gaia last and named its limitations too.

What to Think About Before You Share

Before you connect any app to a partner, it helps to know what you actually want out of it. Here's what tends to matter most.

Why You Want to Share

The reason changes what you need. A PMS heads-up is a light, low-stakes share. Coordinating a fertile window while trying to conceive needs more precision. Helping a partner understand perimenopause symptoms might call for more context than a calendar can give. Get clear on the "why" first, because it points you toward the right level of detail.

How Much You Want Them to See

There's a real difference between "my period is due Thursday" and "here's every symptom and mood note I've logged for six months." Some apps only offer one end of that range. Others let you pick. Decide what you're comfortable with before you connect anything.

Whether It's One-Way or Two-Way

Most partner features are one-directional: you share, your partner views. A couple of apps, like Glow, are built for both people to log and see each other's data. Neither approach is wrong, but they're different arrangements, so it's worth knowing which one you're setting up.

How Easy It Is to Undo

Circumstances change. A good partner-sharing feature makes it just as easy to stop sharing as it was to start. Every app in this guide lets you disconnect from your settings, but how obvious that option is varies, and it's worth checking before you commit to sharing anything.

Step 2: The 6 Ways to Share Compared

For a Free, Light Heads-Up: Flo for Partners

Best if you want: A simple, no-cost way to give a partner visibility into your cycle and pregnancy without an extra subscription.

What's Shared

• Cycle predictions and phase, or pregnancy progress if you're using Flo's pregnancy mode
• Push notifications, symptom explanations, and tips for how your partner can support you
• Educational content and short quizzes aimed at your partner, not at you

Who Controls It

You do. Flo for Partners is a feature inside your own Flo account, and you decide whether to set it up and what gets shared. Your partner gets a read-only view.

How to Revoke

You can unlink the connection from your Flo account settings at any time, which removes your partner's access going forward.

Strengths

• Completely free, on both sides, no Premium subscription required
• Built around education for the partner, not just raw data, with tips on how to be supportive
• Works for both cycle tracking and pregnancy

Limitations

• Flo settled with the FTC in 2021 over past data sharing with third-party analytics and ad platforms, and a related class action against Flo, Google, and Flurry has preliminary court approval for a combined $59.5 million settlement, with a final approval hearing set for October 2026. Flo has since added privacy commitments and an opt-in Anonymous Mode, and there's no indication it currently sells user data, but it's worth knowing that history
• Anonymous Mode, Flo's heightened-privacy option, requires a paid subscription
• The partner view leans toward general cycle and pregnancy status rather than detailed symptom logs

Who Should Choose This

• You want your partner to have a general sense of your cycle or pregnancy without a deep symptom log
• You don't want to pay anything for either side of the connection
• You'd like your partner to get some coaching on how to be supportive, not just data

Pricing: Free for both the Flo account holder and the connected partner.

Download: Available on iOS and Android

For the Most Limited Data Exposure: Clue Connect

Best if you want: To share timing, not detail. Clue Connect shows the calendar, not the diary.

What's Shared

• Period days, fertile days, ovulation, and PMS days, shown in a simple calendar view
• That's it. Mood, energy, pain, and any other experiences you've logged in Clue stay private and don't appear to your connection

Who Controls It

You do, and the scope of what's shared is fixed by Clue rather than customizable. You choose whether to connect, not what within that calendar view gets shown.

How to Revoke

You can end the connection from Clue's settings at any time.

Strengths

• Clue is widely regarded as a privacy-forward choice among period apps, and its data-minimal approach to partner sharing reflects that
• Simple to understand: there's no ambiguity about what your partner can and can't see
• The person you connect with doesn't need a paid subscription to view your calendar

Limitations

• Sharing requires a Clue Plus subscription on your end, currently $39.99/year
• You can only connect with one person at a time
• Not available if you're using Clue's pregnancy mode
• No way to share more than the fixed calendar view, even if you'd want to

Who Should Choose This

• You want your partner to know your cycle timing and nothing more
• You value a data-minimal approach to sharing by default
• You're not currently pregnant and only need one connection

Pricing: Clue Plus is required to share, currently $39.99/year. The connected partner uses the free version of Clue.

Download: Available on iOS and Android

For Two-Way TTC Coordination: Glow

Best if you want: Both partners logging and both partners seeing the same fertility picture, especially while trying to conceive.

What's Shared

• Shared alerts on ovulation day, period start and end, and the fertile window
• Shared access to Glow's percent-chance-of-pregnancy estimate and cycle calendar
• Each partner's own health logs, weight, and lifestyle factors that Glow uses to generate fertility tips for both of you

Who Controls It

Once you add a partner by entering their name and email and they accept, the connection is two-way: health data from your account is shared with your partner's account, and vice versa. This is a different arrangement than the one-way apps in this list, so both people should be comfortable with it before connecting.

How to Revoke

You can remove the partner connection from Glow's account settings, which stops the two-way data flow.

Strengths

• Built specifically for couples trying to conceive, with fertility tips for both partners, not just the person tracking their cycle
• Removes the back-and-forth of relaying ovulation timing manually
• Both partners get insight into how their own habits affect fertility

Limitations

• Because it's bidirectional, both people's data is visible to the other, which is more exposure than a one-way share
• Best suited to conception-focused tracking rather than general symptom or mood sharing
• Some deeper insights sit behind Glow Premium

Who Should Choose This

• You and your partner are actively trying to conceive
• You want a shared calendar instead of relaying dates back and forth
• You're comfortable with a two-way data connection rather than a one-way share

Pricing: Free to connect. Glow Premium runs around $69.99/year, with quarterly and lifetime options also available. Confirm current pricing in-app.

Download: Available on iOS and Android

For Customizing Exactly What's Visible: Natural Cycles NC° Partner View

Best if you want: Fine control over what your partner sees and how far back their view goes.

What's Shared

• Your daily fertility status (typically shown as a simple indicator of fertile versus non-fertile days)
• Optional additional info you choose to include
• You can set how far back your partner's view extends and what exactly appears in it

Who Controls It

You do, in detail. Partner View is opt-in, and Natural Cycles lets you customize both the depth of history and the specific information visible, which is more granular control than most apps in this list offer.

How to Revoke

You can disable Partner View immediately from the app's settings, which cuts off access right away.

Strengths

• The most customizable sharing scope of any app here, letting you decide exactly what's visible rather than accepting a fixed view
• Useful for couples using Natural Cycles as a form of digital birth control, since a shared daily status keeps both partners on the same page
• Also useful for couples trying to conceive, since your partner can see when your fertile window falls

Limitations

• Natural Cycles itself is a paid app, with pricing that has varied by source and region, so check the current subscription cost before committing
• Some Natural Cycles use cases are tied to digital birth control claims, which have their own FDA clearance and correct-use requirements. It's not interchangeable with a symptom or mood tracker
• Built primarily around fertility status, so it's not the tool for sharing broader mood or symptom context

Who Should Choose This

• You want granular control over exactly what your partner sees and for how long
• You're using Natural Cycles for conception planning or as your chosen form of digital contraception
• You want a daily, simple status your partner can check without a detailed log

Pricing: Reported pricing has ranged roughly from $13.99/month to $21.99/month depending on source and region, with annual plans also available. Confirm current pricing directly in the app before subscribing.

Download: Available on iOS and Android

For General Health Sharing Without a Cycle App: Apple Health

Best if you want: To share broader health data with a partner or caregiver without adopting a dedicated cycle-tracking app.

What's Shared

• Whichever categories you choose from your Health app data, such as heart rate, sleep hours, exercise minutes, and lab results
• Health alerts and trends, including notifications like high heart rate or irregular rhythm
• Which categories are available to share has shifted across iOS versions, so check your own Health app's Sharing tab for the current list rather than assuming cycle tracking specifically is included

Who Controls It

You do. From the Sharing tab, you search your contacts, select who to share with, and choose either suggested topics or set categories up manually.

How to Revoke

You can stop sharing with a specific person, or stop sharing a specific data category, at any time from the Sharing tab.

Strengths

• Already built into iOS, so there's nothing new to download if you're already using an iPhone
• Covers a wide range of health data beyond just cycle information, which can be useful for caregivers or family members, not only romantic partners
• Apple's general privacy stance is that health data is encrypted and not used for advertising

Limitations

• Not built specifically for cycle or period sharing, and whether cycle tracking data appears among shareable categories isn't consistent or clearly documented across iOS versions
• Requires the person you're sharing with to be in your Contacts and have an Apple device
• Less purpose-built guidance or education for a partner compared to apps designed specifically around cycle sharing

Who Should Choose This

• You want to share general health trends, not specifically cycle data
• You're sharing with a caregiver or family member as well as, or instead of, a romantic partner
• You'd rather not add another app just for sharing

Pricing: Free, built into iOS.

Setup: Available on iPhone through the built-in Health app's Sharing tab.

For Sharing Cycle Data Alongside Everything Else You Track: Go Go Gaia

Best if you want: A partner connection that lives inside the same app where you're already tracking your cycle, mood, symptoms, and more.

What's Shared

• You connect with a partner through an invite link, and you choose what to share from there
• Sharing is selective. You send an invite for the specific information you want a partner to see, rather than opening your entire log by default

Who Controls It

You do. The connection is invite-based, and you control what gets shared and can revoke access.

How to Revoke

You can revoke a partner's access to shared data from within the app.

Strengths

• Because Go Go Gaia already tracks cycle, mood, symptoms, nutrition, fitness, and sleep in one place, sharing doesn't require a separate app just for the partner feature
• The invite-and-choose model means you're not defaulting into a fixed, one-size view like some competitors
• Free to use, with 1-click logging on your side making it easy to keep the shared picture current

Limitations

• iOS only, no Android version yet, so your partner also needs an iPhone
• Newer partner-sharing feature with a smaller track record than Flo for Partners or Clue Connect, which have been refined over several years
• If you specifically want the most battle-tested, widely reviewed partner feature, Flo or Clue currently have more history to point to

Who Should Choose This

• You're already tracking cycle, mood, symptoms, or fitness in one app and don't want a second app just to share with a partner
• You want to choose what you share rather than accept a fixed calendar view
• You and your partner both use iPhone

Pricing: Free to download and connect with a partner.

Download: Available on iOS App Store

Feature Comparison Table

Here's how the 6 sharing options stack up on what matters most for privacy and control:

Step 3: Making Your Decision

Here's the bottom line for each option:

Privacy Considerations

Sharing health data with a partner is different from sharing it with an app. The app's privacy policy tells you what the company does with your data. The sharing feature is about what a specific person in your life gets to see, and that deserves its own thought.

• Check what's shared by default versus what you choose. Clue Connect and Flo for Partners largely show a fixed view. Natural Cycles and Go Go Gaia are more selective, letting you pick what's visible.
• Know whether it's one-way or two-way. Glow's connection goes both directions. If you'd rather your partner not see your logs while you see theirs, a one-way app is the better fit.
• Understand each company's data practices, separate from the sharing feature. Flo's 2021 FTC settlement and the related $59.5 million class action against Flo, Google, and Flurry (preliminary approval April 2026, final hearing set for October 2026) are both worth knowing about, even though they concern third-party data sharing with advertisers rather than the partner feature itself. Clue has generally been positioned as privacy-forward among period apps. Read the current privacy policy for whichever app you choose, since practices and disclosures do change over time.
• Confirm how to revoke access before you share anything. Every app here lets you undo a connection, but knowing exactly where that setting lives before you need it saves stress later.
• Talk about it with your partner, not just the app. A revoke button doesn't undo a conversation. Agree on what you're both comfortable sharing before you connect anything.

Tips for Getting Started

Whichever app you choose, here's how to set up partner sharing well:

1. Start narrow. You can usually share more later, but it's harder to walk back an overly broad share. Begin with cycle timing and expand only if you both want to.
2. Read the actual sharing settings before you invite anyone. Don't assume what's shared. The apps in this guide vary a lot, from Clue's fixed calendar view to Natural Cycles' fully custom scope.
3. Set expectations together. Tell your partner what they're about to see and why, so it doesn't feel like a surprise or a data dump.
4. Revisit it if your reason for sharing changes. A PMS heads-up during a stressful season is different from ongoing TTC coordination. It's fine to adjust what's shared as your situation changes.
5. Know the off switch before you need it. Confirm where the revoke setting lives in whichever app you pick, so you're not searching for it under pressure.

Frequently Asked Questions

Can I share my period tracker with my partner?

Yes. Flo for Partners, Clue Connect, Glow's partner connection, Natural Cycles' NC° Partner View, and Go Go Gaia all let you invite a partner to see some version of your cycle. Apple's Health app has a general Sharing tab too, though it's built for health data broadly rather than cycle tracking specifically. Each app controls what's shared differently, so it's worth checking before you assume your partner sees everything you log.

Does Flo for Partners cost money?

No. Flo for Partners is a free feature inside the standard Flo app and doesn't require a Premium subscription on either side. Flo settled with the FTC in 2021 over data sharing with third-party analytics services, and a related class action against Flo, Google, and Flurry got preliminary court approval for a combined $59.5 million settlement in April 2026, with a final approval hearing set for October 2026. Since then, Flo has added an opt-in Anonymous Mode, though that heightened-privacy option sits behind a paid subscription.

What exactly does my partner see when I use Clue Connect?

Clue Connect shows your connection your basic cycle phases in a calendar view: period days, fertile days, ovulation, and PMS days. It doesn't show mood, energy, pain, or any other symptoms you've logged. Sharing requires a Clue Plus subscription on your end, currently $39.99/year, while the person you share with can view it on the free version of the app. You can only connect with one person at a time, and it isn't available in pregnancy mode.

Can I stop sharing my cycle data with my partner once I've started?

In every app covered here, sharing is something you turn on and can turn back off. Natural Cycles lets you disable Partner View immediately from settings. Clue Connect and Flo for Partners can both be unlinked from the app's settings menu. Apple Health sharing can be stopped per person, per data category, from the Sharing tab. Go Go Gaia's partner connection works the same way: you control it and can revoke it.

Is it safe to share cycle or health data with a partner through an app?

The apps themselves generally build partner sharing to be one-directional and revocable, which is the safer design. The bigger question is usually about trust between you and the person you're sharing with, not the technology. Think about what you're comfortable with someone else seeing, whether that's just period timing or more detailed symptoms and mood, and pick a sharing level that matches.

What should couples trying to conceive track together?

Many TTC couples find it useful to share the fertile window and ovulation timing so both partners are working from the same calendar instead of one person relaying dates. Glow's partner connection and Natural Cycles' Partner View are both built with this in mind. Sharing symptoms or mood is a personal choice on top of that, not a requirement. No tracking app should be relied on to confirm pregnancy or rule it out. A pregnancy test and your doctor are the way to do that.

Does Apple Health sharing include cycle tracking data?

Apple's Health app has a general Sharing tab that lets you choose specific categories, like heart rate, sleep, exercise minutes, and lab results, to share with a contact. Which categories are available to share has shifted across iOS versions, so check the Sharing tab on your own device rather than assuming cycle tracking is or isn't included. If you specifically want to share cycle information, a dedicated period or cycle app with a built-in partner feature is a more predictable choice.

Final Thoughts

There's no single right way to share your cycle with a partner, because people share for different reasons. If you want the lightest lift and zero cost, Flo for Partners covers the basics. If you want your partner to know timing and nothing more, Clue Connect is the most data-minimal option. If you're both actively trying to conceive, Glow's two-way connection removes the manual back-and-forth. If you want granular control over exactly what's visible, Natural Cycles' Partner View gives you the most say. And if you're already tracking your cycle alongside mood, symptoms, and habits somewhere, Go Go Gaia's invite-based sharing keeps that context together instead of splitting it across two apps.

Whichever you choose, the setting itself is only half the equation. The other half is the conversation you have with your partner about what you're comfortable sharing, and why. Start narrow, talk it through, and expand from there if it feels right.
