Clue is GDPR-compliant, so why switch

GDPR compliance means Clue follows rules about how cloud data is handled. It does not change the fact that cloud data exists. A server holding cycle data can be subpoenaed, breached, or subjected to a policy change. An on-device tracker removes the server from the equation entirely, which is a stronger privacy posture than any compliance regime can offer.

Can Clue data be subpoenaed for a reproductive-rights case in the US

Clue is Berlin-based, which provides some distance from US subpoenas, but not immunity. US courts can seek mutual legal assistance treaty (MLAT) cooperation for data held abroad, and Clue has stated it would challenge such requests. The challenge is not a guarantee. On-device tracking removes the subpoena target because there is no server-side copy to produce.

Will I lose my period predictions when I switch

Temporarily. Every tracker needs 2-3 recorded cycles to calibrate its prediction algorithm. Seeding the new app with your last 3-6 cycle start dates from the Clue export minimizes the calibration gap. After two full cycles with the new app, predictions are usually back to baseline accuracy.

How to Switch from Clue to a Private Period Tracker

Export your Clue cycle history, delete the account under GDPR, file a formal data request, and move to an on-device tracker that cannot be subpoenaed.

Why switch from Clue Clue has the cleanest privacy record among the major period trackers. No FTC enforcement action, no class action settlement, no documented history of selling data to advertisers. Berlin based and GDPR native, Clue built its brand on being the responsible option in a category where responsibility was scarce. That record is real. It is also a weaker protection than most users know. Clue stores your cycle history on its servers. A server copy of your data exists whether or not Clue behaves responsibly with it. A server copy can be subpoenaed. It can be breached. It can be caught up in a policy change or an acquisition. The strongest privacy guarantee Clue can offer is "we handle your data carefully." An on device tracker offers a different guarantee: "there is no off device copy to handle." If you are on Clue because it felt like the safest cloud tracker, and you are now thinking through subpoena risk after Dobbs or data broker sales after the Flo settlement, this guide is the clean exit.
