Fertility insights

Last updated 25 October 2026

This is an optional research view for organizing observations—not a fertility test, contraception method, diagnosis, or promise about a person’s body. It is separate from ordinary cycle tracking and the private journal, and can remain off.

Development status

Dry is not publicly shipped. Experimental fertility insights are being specified and tested, and availability may differ between pre-release builds. This page states the safety and information contract the feature must meet; it is not a claim that every input or integration is available today.

Possible inputs

The view may use confirmed period history and manually entered basal body temperature (BBT), cervical-mucus observations, ovulation test results, progesterone test results, pregnancy test results, and contraception records. Optional age and weight context may help explain why an output is limited, but neither is required.

Where a tested build includes HealthKit integration, BBT samples may be read only after a separate Apple Health permission. Manual and HealthKit values must remain distinguishable. A stored test result is the result the person recorded; Dry does not turn it into laboratory verification or a diagnosis.

Source and confidence stay visible

Each insight should identify which kinds of observations contributed, whether a value was entered manually or read from HealthKit, and how recent and complete the relevant history is. User-entered and imported values are not silently merged into an unexplained answer.

Confidence describes the completeness and consistency of the available record for that limited insight. It is not a probability of conception, proof of ovulation, an accuracy guarantee, or a measure of contraceptive effectiveness.

Missing or conflicting information

Missing observations remain unknown. Dry must not invent a temperature, assume a missing test was negative, treat an unrecorded contraceptive method as “not used,” or fill gaps with a population average. Sparse, stale, irregular, or conflicting inputs should produce “Not enough information” or a visibly limited result—not false precision.

What the view cannot tell you

Calendar history and home observations cannot reliably identify a “safe day,” rule pregnancy in or out, confirm ovulation, diagnose a condition, or say when conception will occur. Dry must not label any day safe for unprotected sex or recommend starting, stopping, or changing contraception.

Do not use Dry to make contraceptive or medical decisions. A clinician or the instructions supplied with a regulated test can provide guidance appropriate to an individual situation. Seek urgent medical help when symptoms or circumstances require it rather than waiting for an app insight.

Acknowledgement and choice

Enabling the experimental view should require a clear acknowledgement of its purpose, inputs, uncertainty, and limits. That acknowledgement is informed consent to use an optional feature. It is not a blanket liability waiver, does not remove Dry’s privacy or safety obligations, and does not transfer responsibility for misleading design to the user.

The feature can be declined or disabled without disabling cycle tracking or the journal. Turning it off should hide its outputs without silently deleting entered observations; deletion remains a separate, explicit data-control action.

Privacy

These are sensitive health records. The same local-first protections and explicit deletion controls described in Dry’s privacy noticeapply. HealthKit access, if introduced, must be narrowly permissioned, explained before access, and reviewed against Apple’s health-data rules before public release.
