PREMIUM โ€” PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. Mark the days you bleed on a clean calendar and CycleLog shows when your next period is likely due โ€” with no account, no cloud, and no one else ever seeing a single entry. Most period apps want your email, your consent to analytics, and your cycle history on their servers. CycleLog is the opposite: every entry is stored on your iPhone only. There is no sign-up, no sync, no ad SDK, and nothing is sent anywhere. Turn on the Face ID lock and even someone holding your unlocked phone sees nothing. WHAT YOU GET โ€ข Open the app to "Day 14" and "Around Sep 2, about 6 days away" โ€” no counting backwards through a paper calendar โ€ข A month view where logging a day takes one tap: period, spotting, cramps, mood swings, fatigue, or a short note โ€ข An estimate that stays honest โ€” it tells you how many of your own logged cycles it is built on, and says so plainly when your logging lapses instead of pretending โ€ข A reminder up to 3 days before your estimated date, with discreet wording so your lock screen never shows the word "period" โ€ข Charts of how often each symptom appears and how much your cycles vary โ€” drawn only from what you logged โ€ข Your whole history exported as a CSV you can hand to a clinician, and a delete-all button that actually deletes PERFECT FOR โ€ข Anyone who wants period dates written down without handing them to an ad-funded platform โ€ข Anyone who needs the app itself to stay discreet โ€” Face ID or passcode lock, neutral notification wording โ€ข Irregular loggers: a missed month never corrupts your record, the estimate simply picks up at your next entry โ€ข Anyone whose doctor has asked "when was your last period?" one time too many WHY NOT JUST USE THE BIG-NAME TRACKERS? The famous apps are built around accounts and data. Your cycle history sits on their servers, subject to their policies and their breaches. CycleLog has no server to breach: entries never leave your iPhone, and the app works entirely offline. Its dates are estimates from the days you logged โ€” not medical advice and not a diagnosis. Anything that worries you belongs with a clinician, and the app says exactly that. PRIVATE BY DEFAULT No account. No cloud. No analytics or ad SDKs. An optional Face ID / passcode lock guards the app, reminders can use neutral wording, and export and deletion are built in โ€” your record belongs to you, on your device, full stop. PREMIUM (PURCHASE REQUIRED) CycleLog Pro unlocks symptom pattern analysis: which day of your cycle each symptom usually lands on, worked out from your own log. Choose the weekly or yearly subscription, or a one-time lifetime purchase. Logging, the calendar, your estimate, reminders, export, and deletion all work without Pro. Log today before you put your phone down โ€” your next-period estimate begins with the very first entry.
