Period trackers you can use without an account

By the AYWA teamPublished October 19, 2026Last checked October 19, 2026

AYWA makes a period tracker, and it’s one of the options here. We say so wherever it comes up, and every fact about another app links to that company’s own page.

Why skip the account?

An account links your cycle records to an identity: an email address, a name, a sign-in. That’s what lets a company restore your data on a new phone. It also means the records sit with that company, tied to you.

Plenty of people would rather their period dates stay on their own phone, especially in the US since 2022. Some just don’t want another login. Either is a reasonable choice. The point is to choose knowingly.

Apps that work without one

Apple Health: Cycle Tracking

Built into the Health app (Browse → Cycle Tracking), with no separate sign-up. Apple says Health data is encrypted on your device and protected by your passcode, Face ID or Touch ID. If you sync Health with iCloud, it’s encrypted in transit and at rest, and end-to-end encrypted when two-factor authentication is on, which is the default.

Euki

Euki has no user accounts at all and doesn’t collect your email. It says your data is stored only on your device, with no servers and no cookies, and it works offline. You can set a PIN. Deleting the app deletes your data everywhere.

drip

Open source, with no account. drip says everything you enter stays on your device, and its prediction maths is published for anyone to check.

AYWA (ours)

No account needed. Your records are stored on your iPhone, there are no ads and no tracking, and Ask AYWA (the optional AI feature) is off until you turn it on. If you want a backup or to move to a new phone, you can add an account later with Sign in with Apple or email; the backup is encrypted, and you can delete it any time.

Flo, with Anonymous Mode

Flo normally uses an account (email, Apple or Google). Its Anonymous Mode lets you use Flo without your name, email or technical identifiers linked to your health data. The catch, by Flo’s own help centre: an anonymous account can’t be restored if you log out or change phones, and you must register before Flo can send you an export.

Clue: account required

Clue used to work without an account. Since 2019 it requires a free one, and stores your data on its EU-based servers so you can restore it on a new phone.

Side by side

The backup trade-off

No account usually means nobody can restore your records for you. Clue gives exactly this as its reason for requiring accounts: phones get lost or stolen. Euki is upfront that deleting the app deletes everything.

You can keep privacy and still protect your history:

• Export now and then. If your app can export a file, save a copy in a private place. In AYWA it’s You → Privacy & your data → Export my records.
• Write down your period start dates every few months. If everything else is lost, those dates are what a new app needs for its estimates.
• Use a backup that only you control, like Apple Health’s end-to-end encrypted iCloud sync, or an optional encrypted backup you can delete.

A two-minute privacy check for any app

1. Read the App Store privacy label (“App Privacy” on the app’s page). Look for “Data Linked to You” and “Data Used to Track You”.
2. Find the words “stored on your device” or “servers” in the privacy policy.
3. Check whether an account is required, and what it’s for.
4. Check export and delete. Can you take your records and delete them yourself, without emailing support?
5. Check what any AI feature sends, and whether it’s on by default.
