If you don’t want to hand over an email address to track your period, you have good options. Euki is the one we’d pick for most people. It’s free, it needs no account, email or phone number, and everything you log stays on your phone. drip., PrivateCycle and Apple’s own Cycle Tracking work without a sign-up too, and Periodical does the same on Android. Every one of them keeps your data on the device, so they all work offline.
We make Plum, which does need an account, so we’ve no reason to oversell any app on this list. Every claim below comes from the app’s own listing, site or help pages, read on October 12, 2026.
Which period trackers work without an account?
| App | Account needed? | Works offline? | Platforms | Price |
|---|---|---|---|---|
| Euki | No | Yes, data stays on the phone | iPhone, Android | Free |
| drip. | No | Yes, data stays on the phone | iPhone, Android | Free |
| PrivateCycle | No | Yes | iPhone | Free, $19.99 one-time upgrade |
| Periodical | No | Yes, no internet access at all | Android | Free |
| Apple Cycle Tracking | No sign-up, iCloud backup uses your Apple Account | Yes, data stays on the phone | iPhone, iPad, Apple Watch | Free, built in |
| Flo, Anonymous Mode | No name or email, but Flo still keeps an account | No, data is held by Flo | iPhone, Android | Free, paid Premium |
| Clue | Yes, for new users | No, data syncs to Clue’s servers | iPhone, Android | Free, paid Clue Plus |
| Plum | Yes, Apple or Google | No, logging needs a connection | iPhone | Free, paid Premium |
Euki
Euki’s App Store listing says plainly that you don’t need an account, email or phone number, and that your data is stored on your device and nowhere else. You can set a PIN to lock it. It’s run as a nonprofit, and its site says it’s free with no paywalls, in English and Spanish, on iPhone and Android. Its privacy label reads Data Not Collected. Neither the site nor the listing mentions an export or backup, and that’s the catch we’d weigh before picking it.
drip.
drip. is an open-source tracker whose site says everything you enter stays on your device. Unlike Euki, it lets you export and import your data and password-protect it, which the App Store listing and its F-Droid page both mention. It’s free, it runs on iPhone and Android, and its label also says Data Not Collected. If you want no account and still want a way to keep a copy, this is the better pick.
PrivateCycle
PrivateCycle is iPhone only and the most thorough about offline use. Its listing says there’s no sign-up, that data sits in an encrypted database on the phone, and that tracking and predictions work without internet. It has a passphrase-protected backup and exports to JSON, CSV or plain text. The core app is free. A one-time $19.99 upgrade adds extra insights and a report for your clinician, with no subscription.
Periodical, for Android
Periodical is a small open-source Android calendar for periods. Its developer says it doesn’t ask for internet access at all, so nothing can leave the phone even by accident. It saves a backup file to your phone’s storage or a memory card, which you can copy somewhere safe. It’s free on Google Play and F-Droid. There’s no iPhone version.
Apple Cycle Tracking
Every iPhone already has a period tracker in the Health app. Cycle Tracking logs periods and symptoms, predicts your next period and fertile window, and works on iPhone, iPad and Apple Watch. There’s nothing to sign up for. Apple’s privacy page says Health data is encrypted when the phone is locked. If you back up to iCloud with two-factor authentication on, Apple says it can’t read that backup. Our guide to Apple Health cycle tracking goes further into it.
Do Flo and Clue work without an account?
Clue doesn’t, for anyone joining now. Clue says it has asked new users to create an account since 2019, so their history can live on its EU servers and come back on a new phone. You’ll find older advice online about using Clue without signing up. That applied to the old app.
Flo sits in between. Anonymous Mode lets you use the app without a name or email, and Flo says it then can’t tie your health data to you. Flo still creates an account for you, though, and your data still lives with Flo. It also says it can’t recover an Anonymous Mode history if your phone is lost, damaged or stolen. Flo for Partners and wearables like Apple Watch don’t work in that mode. So it hides who you are, but you don’t get the on-device setup or the backup. If Flo’s history worries you, our page on whether Flo sells your data lays out what’s on the record.
What do you give up without an account?
No account means no company holds your cycle. That’s the whole appeal. The same fact takes three things away.
- A backup you don’t have to think about. If the phone is lost, broken or wiped, an on-device app’s history goes with it unless you made a copy.
- An easy move to a new phone. A synced app restores when you sign in. An on-device app needs you to export and import, or to restore a whole-phone backup.
- Sharing. None of the on-device apps above lets a friend or partner see your dates. Sharing needs a server in the middle, and a server needs to know who you are.
Predictions don’t suffer much. Each app works out your next period from the dates you log, and that math runs fine on the phone. Our page on how accurate period apps are covers what makes the bigger difference.
How do I back up a period tracker that has no account?
Pick an app that can export, and then actually do it. Once a month, right after you log a period, is easy to remember.
- In drip., use its export and save the file to somewhere that isn’t the phone, like a computer or a cloud drive you trust.
- In PrivateCycle, make a passphrase-protected backup, or export a CSV if you want something you can open anywhere.
- In Periodical, save a backup to storage and then copy the file off the phone. A backup that stays on the same phone won’t help if the phone is gone.
- For Apple Cycle Tracking, turn on iCloud backup for Health, or back up the iPhone to a computer with encryption switched on. Apple’s backup article says only encrypted computer backups include Health data. You can also export your cycle history as a PDF from the Health app.
If you use Euki, keep a plain note of each period’s start date somewhere else. It’s low-tech, and it means a lost phone costs you the details but not the dates a doctor will ask about.
How to choose
Start with how much a lost history would hurt. If it wouldn’t, pick Euki. It’s the simplest and asks for nothing. If you want no account but would hate to start over, pick drip. or PrivateCycle and export regularly. On Android with no Google sign-in at all, Periodical is the cleanest. If you already live in the Health app and back up to iCloud, Apple’s Cycle Tracking gives you no sign-up and a backup in one go.
If what you really want is privacy rather than no account as such, the two aren’t the same thing. Some synced apps handle data well, and an on-device app is only as safe as your phone’s lock. Our guides to whether period tracker apps are safe and to choosing a private period tracker go through what to check.
Where Plum fits
Plum is not a no-account app. You have to sign in with Apple or Google, and there’s no email-and-password option. As our devices and sign-in page explains, your history lives on Plum’s servers, encrypted in transit and at rest. That account is what brings your history back on a new iPhone and lets a group of friends see each other’s period days. It also means Plum needs a connection to save what you log, and there’s no export yet. If no account is a must, one of the apps above will suit you better.
You can still use our free tools without signing up for anything. The period calculator, cycle phase calculator and irregular period calculator all run in your browser, with no account and nothing to install.
