SyncHer Privacy Policy
SyncHer is a cycle and relationship companion created by Decodation LLC. The app helps users track cycle context, mood, symptoms, energy, notes, and relationship-support preferences. Privacy and consent are central to the product: partner access is limited to what the account owner chooses to share.
Information We Collect
- Account information, such as email address, display name, user role, and authentication identifiers.
- Cycle profile information, such as last period start date, average cycle length, and average period length.
- Daily check-in information, such as mood, energy, pain, stress, symptoms, sharing choices, and notes.
- Period and body-signal logs, such as flow, symptoms, basal body temperature, cervical fluid, ovulation tests, and pregnancy tests if the user enters them.
- Partner-connection information, such as invite codes, couple status, and sharing settings.
- Notification information, such as FCM tokens and notification records.
- AI insight records generated from user-provided context and privacy settings.
- Store purchase identifiers, product, renewal and expiry status used to verify optional subscriptions. Apple or Google handles payment details; we do not receive your card number.
- Operational information, such as server request status, timing, security events and AI usage counters, used to keep the service reliable and limit abuse and costs.
- Optional mobile crash and error reports, including technical stack traces, app and device information, installation identifiers and an account identifier when associated by the authentication integration.
How We Use Information
- To provide cycle estimates, check-ins, dashboards, insights, reminders, and relationship-support suggestions.
- To connect partners only when an invite code is accepted.
- To apply privacy settings before showing any partner-facing content.
- To generate supportive AI insights through server-side systems without exposing private API keys in the app.
- To improve reliability, security, and user experience.
Partner Sharing
The account owner controls what a partner may see. Notes are private by default. Partner tips can be generated without exposing raw health details. If cycle phase, mood, symptoms, energy, notes, or AI tips are hidden by privacy settings, they should not be shown to the partner.
AI Insights
With your permission, SyncHer sends your AI request to OpenAI through a secured server connection. You can optionally include your latest check-in's mood, energy, symptoms, pain, stress and estimated cycle phase. Journal notes are not automatically sent. Any text you type into the AI request is sent, so avoid including information you do not want processed by the provider. The personal assistant never loads a partner's private health records.
You may separately enable daily AI reflections, which use your check-in fields or the privacy-filtered context allowed for a partner. Partner opt-in alone does not authorize processing of the woman's health context: her daily AI consent is also required. You can turn daily AI off in the AI companion. Personal assistant replies are saved privately in SyncHer; raw assistant prompts are not saved in our conversation records. Requests are sent with API response storage disabled, but provider security and abuse-monitoring retention can still apply. See OpenAI's API data controls.
SyncHer may use AI to generate reflections and support suggestions. AI outputs are intended for general wellness and relationship support. They are not medical advice, diagnosis, treatment, or a substitute for a healthcare professional.
Health And Safety
Cycle predictions are estimates and may be inaccurate. If symptoms are severe, unusual, or concerning, consider speaking with a qualified healthcare professional.
Data Sharing
We do not sell personal information. We may share information with service providers that help operate the app, such as Firebase for authentication, storage, functions, hosting, and messaging. Partner-visible content is limited by the user's sharing settings.
Data Security
We use Firebase Authentication, Firestore security rules, and server-side functions to protect user data and enforce access limits. No method of transmission or storage is perfectly secure, but we design SyncHer to reduce unnecessary exposure of private information.
Reliability And Diagnostics
Our servers record technical request and error information. AI provider telemetry uses fixed outcome labels, timing and token counts, not your prompt, journal text, health fields, email or authentication tokens. Per-account AI usage counters enforce request limits; new counters expire from the database after seven days, subject to background deletion processing. This does not delete your saved check-ins or insights.
Mobile versions that include Firebase Crashlytics offer optional crash diagnostics in Settings. Collection is off by default on a fresh installation and starts only after you turn it on. Reports help identify crashes and technical errors. They can include app version, operating system, device and installation information, technical stack traces and a Firebase account identifier; they must not be treated as anonymous. We do not intentionally add journal notes, AI prompts, health details, email addresses or authentication tokens to diagnostic reports. Google Firebase processes these reports as our service provider. Google Analytics is not included.
You can turn crash diagnostics off in Settings. This disables automatic report transmission and requests deletion of unsent local reports; it does not recall reports already transmitted to Firebase. Technical reports are used for app reliability, not advertising, partner monitoring or cross-app tracking.
Your Choices
- You can update sharing settings in the app.
- You can stop sharing partner insights by changing privacy controls.
- You can choose whether to enable optional mobile crash diagnostics.
- You can request permanent account deletion in Settings > Delete account, or use Data Deletion for help. Deletion ends partner sharing and removes your health records. It does not cancel a store subscription.
Children
SyncHer is intended for adults aged 18 and over. It is not intended for children.
