# Features Synced combines simple period tracking with optional ways to understand and share your cycle. The basics work without daily symptom logs, and advanced modules stay hidden until you enable them. Last updated: 2026-11-10 ## What comes with the simple experience? Record a period start, adjust dates in your calendar and keep your full history. Today shows a cycle ring and a countdown based on the dates you have recorded. Daily logs are available when you want to note a symptom or mood, but they are not required to keep using Synced. Predictions are estimates that can change as more history arrives. The calendar lets you correct or backfill dates so an old entry does not have to become a permanent mistake. ## Which features can I add later? Customize offers body signs, forecasts, phase tips and life-stage options. You can choose reminders, prepare a doctor report, import supported files or use the separate Ask Synced assistant after consent. Circle sharing has its own permission choices; enabling a module does not automatically disclose it to someone else. Couples planning requires both people to opt in through an active partner share. Each feature page explains what the feature does and, just as importantly, what it does not promise. ## How can I use this at my own pace? Start with the information you already know and keep the rest optional. Your record does not need to be complete to be useful, and a missing entry should not be treated as evidence that nothing happened. Review your calendar and settings when something looks different from what you intended. Before sharing, choose the smallest view that serves the relationship and check its preview. You can change permissions, pause a connection or stop using an optional module. If a feature raises a health question, take the recorded facts to a qualified professional rather than asking the app to make a diagnosis. ## What should I check before continuing? Check that the dates and choices on your screen reflect what you meant to record. A useful next step is to explore the related feature pages below, then decide whether the simple version is sufficient or an optional setting would help. You never need to turn on every module to use Synced well. For questions about privacy, read the full policies rather than relying on a short feature description. If you want help with an app problem, the Contact page explains what to send without including passwords or private health records. ## What comes with the simple experience? Record a period start, adjust dates in your calendar and keep your full history. ## Does this diagnose a condition? No. Synced organizes your recorded information and estimates; it does not replace individual medical care. ## Can I change what I share? Yes. Each connection has its own permissions, and you can pause or revoke access. Previously saved information cannot be retrieved. ## Explore related pages - [Cycle tracking](/features/cycle-tracking) - [Partner sharing](/features/partner-sharing) - [Doctor report](/features/doctor-report) - [Ask Synced](/features/ask-synced) Educational information, not medical advice.
