Privacy Policy

This policy explains how the SyncHer mobile app (“SyncHer”, “the app”) and this website handle personal data. It is written to meet the EU/UK General Data Protection Regulation (GDPR) and similar laws.

1. Who we are

SyncHer is provided by Rise, Tokiostraße 12, 1220 Vienna, Austria (“we”, “us”). We are the controller of the personal data described in this policy. You can reach us at support@syncher.online.

2. Data we process

2.1 Data that stays on your phone

When you set up SyncHer, you can enter: a nickname for your partner, the start date of her last period, her usual cycle length, favorites (for example takeout or a comfort show), a free-text note, your goals, your reminder time, feedback on tips, and your AI tips choice. The app also stores your subscription status.

This information is stored only in the app's storage on your phone. We don't receive it and can't see it. The daily forecast, built-in tips and reminder notifications are all produced on your phone. Deleting the app, or using Settings → Delete all data, removes it.

Because the app processes information about another person's menstrual cycle, it may be health data. Please only enter information you're comfortable keeping on your phone, and consider being open with your partner about using SyncHer.

2.2 AI tips

AI tips are optional. The app asks for your permission during setup and sends nothing to the AI service unless you agree; you can change your choice at any time in Settings → AI tips. While they are on, the app sends the following to generate a daily tip or a Chat reply:

• the current estimated cycle phase and cycle day;
• the favorites you selected;
• a short summary of which previous tips you marked as helpful or not;
• the day of the week;
• for Chat, your most recent messages in the conversation (up to the last 12, including Wingman's earlier replies), so Wingman can follow up.

We never send her nickname, the actual period dates, your free-text favorites note, or any contact details. Your Chat history is stored on your phone; it is sent only as described above and deleted with Settings → Delete all data. Please don't include names or other identifying details in your messages.

To protect the service from abuse, the app creates an anonymous session the first time it requests an AI tip. This creates a random identifier that isn't linked to your name, email or Apple account. We use it to limit the number of AI requests per install per day. Our server stores only that identifier and today's request count.

Legal basis and your choice: your consent (Art. 6(1)(a)). You can withdraw it at any time by switching AI tips off in Settings → AI tips. The app then uses tips built into the app and stops sending this information; processing that already happened is not affected. SyncHer keeps working either way.

2.3 Subscriptions and payments

Subscriptions are purchased through Apple's App Store (and, once available, Google Play). Apple processes your payment; we never receive your card details. To unlock premium features, the app uses RevenueCat to check your subscription. RevenueCat processes an anonymous app user identifier, purchase and transaction details (such as product, price, currency, dates and store country) and basic device and app information.

Legal basis: performance of our contract with you (Art. 6(1)(b)) and our legitimate interest in preventing fraud (Art. 6(1)(f)).

2.4 Notifications

Daily reminders are scheduled locally on your phone. We don't use a push notification server and don't receive a device token.

2.5 This website

This website doesn't use cookies, analytics or tracking scripts, and loads no third-party resources. Like any web server, our hosting provider processes technical data such as IP address, requested page, time and browser type to deliver the site and keep it secure (legitimate interest, Art. 6(1)(f)).

2.6 Support emails

If you email us, we process your email address and message to answer you (legitimate interest, Art. 6(1)(f)).

2.7 What we don't do

• No advertising, ad identifiers or cross-app tracking.
• No selling or sharing of personal data for marketing.
• No analytics SDKs in the app.
• No automated decisions with legal or similarly significant effects.

3. Service providers

We use the following providers (processors) under data processing terms. They may only use the data to provide their service to us.

AI requests are configured to use only providers that don't retain prompts and don't use them for training. Where data is transferred outside the EU/EEA or UK, we rely on adequacy decisions (such as the EU–US Data Privacy Framework, where the provider is certified) or Standard Contractual Clauses.

4. How long we keep data

• Data on your phone: until you delete it in the app or delete the app.
• AI tip and Chat content: not stored by us after the answer is returned. Our server doesn't log request or response content. Chat history stays on your phone until you start a new chat or delete all data.
• AI rate-limit counter: only the current day's count is kept; earlier days are deleted automatically.
• Anonymous session: until you delete all data in the app. You can also email us to have it removed.
• Subscription records: as long as needed to provide the subscription and meet legal and tax obligations.
• Server and website logs: short-term, according to our providers' log retention.
• Support emails: as long as needed to resolve your request.

5. Your rights

Depending on where you live, you have the right to access, correct, delete, restrict or object to processing of your personal data, to data portability, and to object to processing, including by switching AI tips off. Most data is only on your phone, so you can view, change and delete it directly in the app.

For anything else, email support@syncher.online. Because we don't know who you are, we may need you to share your anonymous identifier or purchase details so we can find the relevant records. You also have the right to lodge a complaint with your local data protection authority.

6. Children

SyncHer is intended for adults. It isn't directed to anyone under 18, and we don't knowingly process children's data.

7. Security

Data sent from the app is encrypted in transit (HTTPS). Server-side access is limited to what each component needs. No system is perfectly secure, so please keep your phone protected with a passcode.

8. Changes to this policy

We'll update this page if our practices change, and change the effective date above. If a change materially affects how we use your data, we'll let you know in the app.
