Optional Cycle Estimates

1. What does this feature do?

Cycle estimates are optional. You can keep a record of your periods without turning estimates on.

If you enable estimates, Planique can show:

• an estimated next period date;
• an estimated ovulation date;
• an estimated fertile window;
• your current cycle day; and
• average cycle and period lengths.

2. What information does Planique use?

Planique uses only the start and end dates of periods you have marked as completed. It looks at up to the six most recent completed cycles and periods.

Planique does not use symptoms, mood, pain, sexual activity, protection information, pregnancy or ovulation test results, notes, other Health information, information from wearables or external services, artificial intelligence, or another user's information to calculate these estimates.

3. How are the dates estimated?

Your average cycle length is based on the number of days between consecutive period start dates. Your average period length is based on the number of days in your completed periods.

Planique estimates the next period by adding the rounded average cycle length to the latest completed period start date. It estimates ovulation as 14 days before the estimated next period. The estimated fertile window runs from five days before through one day after the estimated ovulation date.

At least two completed periods are needed before Planique can estimate dates. The confidence label depends only on how much completed history is available:

• one completed interval provides limited confidence and is not shown as a Calendar prediction;
• two or three completed intervals provide medium confidence; and
• four or more completed intervals provide high confidence.

Planique pauses estimates when the gap since the latest recorded period is longer than 60 days or twice your average cycle length, whichever is longer.

4. What are the important limits?

Calendar averages cannot establish whether or when ovulation occurs. They may not reflect irregular cycles, illness, medication, pregnancy, postpartum changes, perimenopause, individual variation, or missing or inaccurate period records.

Estimates may be wrong. They are for personal organisation only and are not medical advice, a diagnosis, a fertility guarantee or contraception. Do not use them as the sole basis for trying to become pregnant, avoiding pregnancy, treatment or another medical or reproductive decision.

5. What happens when you turn estimates off?

You can turn estimates off at any time. Planique will stop making new estimates and delete the estimated dates and related reminders from active systems. Your period history and other Health records will remain unless you delete them or deactivate Health.
