Privacy Policy

Our Commitment to Your Privacy

Soso is built with privacy as a core principle. We understand that period tracking involves sensitive personal information, especially for young users. We are committed to protecting your data and being transparent about our practices — both inside the Soso mobile app (iOS and Android) and on this website.

Information We Collect

Inside the Soso app

The Soso app does not require an account. The information involved in using the app falls into these categories:

• Your period dates, cycle information, mood, symptoms and personal notes — these are kept entirely on your device and never sent to our servers
• Anonymous usage events — for example, that a feature of the app was used — without the contents of what you logged. These help us understand, in aggregate, how the app is used
• Your Sosô+ subscription status, if you choose to subscribe
• Standard, anonymous mobile signals (such as that the app was installed or opened) used to measure our advertising — see the Meta SDK section below

On this website (forms and quizzes)

When you fill in a form or take a quiz on this website, we collect:

• Your name, email address, and (optionally) your phone number
• The answers you select, the resulting score, and the matched result of any quiz you submit
• The language you took the quiz in and the date and time of submission

Sosô+ Subscription

Sosô+ is our optional paid subscription. It unlocks:

• Unlimited period tracking, with extended cycle forecasts so you can plan further ahead
• Private notes

Subscriptions are processed by Apple (App Store) or Google (Google Play) under their own terms, and your subscription status is managed by RevenueCat, our subscription infrastructure provider. We do not see or store your payment details — only whether your Sosô+ subscription is active.

How We Use Your Information

App data

The information involved in using the app is used to:

• Provide cycle predictions and insights, computed locally on your device
• Display your logged information back to you
• Measure, in aggregate, how the app is used so we can improve it
• Activate the features included in your Sosô+ subscription, when applicable

Website form and quiz data

Information you provide on this website is used to:

• Email you a copy of your quiz result and a magic link so you can revisit it later or compare past attempts
• Add you to our mailing list to occasionally send you updates and content related to Soso. You can unsubscribe at any time using the link in any of our emails.
• In the future, send you updates via WhatsApp or Telegram, only if you provided a phone number

Data Storage and Security

Your period entries, cycle information, mood, symptoms and personal notes are stored locally on your device. They never leave your device — the Soso app does not sync your tracking data to any server, and there is no Soso account to log into.

Anonymous usage events about how the app is used are processed by PostHog (hosted in the European Union) in aggregate, so we can understand which features are working well. These events do not contain the contents of your logs.

Information you submit through forms or quizzes on this website is stored on our servers (Payload CMS hosted on MongoDB Atlas) and processed by Resend, our email and contact-list provider. Both providers are bound by industry-standard data protection commitments.

Notifications

Soso only sends local notifications — reminders scheduled directly by the app on your device (for example, cycle reminders). We do not operate a push notification server, and your device does not register a push token with us or any third party.

Third-Party Services We Use in the App

• PostHog (EU) — anonymous, aggregate product analytics, with no content from your logs
• RevenueCat — manages your Sosô+ subscription status
• Apple App Store / Google Play — process Sosô+ purchases under their own terms
• Meta (Facebook) SDK — measures the effectiveness of our ads; see the section below

On this website (separate from the app) we also use MongoDB Atlas and Resend, as described above.

About the Meta SDK

We include Meta's mobile SDK so we can measure whether our ads on Facebook and Instagram are actually reaching families who want Soso. Without it, we cannot tell which ads work — which means we cannot run them at all, and we cannot reach more families.

The SDK records only standard, anonymous mobile signals — such as that the app was installed, opened, or that a subscription was purchased. It does not receive any of your cycle, mood, symptom or note data. It uses device-level identifiers governed by Apple's App Tracking Transparency prompt and Google's equivalent ad-ID controls, so you are in control.

We do not sell this data. Meta processes it on our behalf strictly for ad attribution. You can disable it at any time in your phone's privacy settings (iOS: Settings → Privacy & Security → Tracking; Android: Settings → Privacy → Ads).

Sharing with Third Parties

We do not sell your information. The data you share with us is treated as confidential.

We share information only with the trusted service providers strictly necessary to deliver our service: PostHog, RevenueCat, the Apple App Store, Google Play, and Meta on the app side; MongoDB Atlas and Resend on the website side. These providers act as our subprocessors and may not use your data for their own purposes.

Your Rights

You have the right to:

• Request a copy of the personal data we hold about you
• Request that we delete your data
• Unsubscribe from our mailing list at any time using the link in any of our emails

Because the Soso app has no account and stores your tracking data only on your device, there is very little for us to delete on the server side — we never collected an identity for you in the first place. The most complete way to delete your in-app data is to use the "Clear all data" button in the app, or to uninstall Soso.

For the anonymous usage events processed by PostHog, you can email us with the anonymous device identifier shown in the app and we will delete the associated events. To cancel a Sosô+ subscription, use your Apple App Store or Google Play subscription settings.

These rights are recognized under Brazil's LGPD, the EU's GDPR, and other comparable data protection laws. To exercise any of them, email us at hello@sosoapp.com.br.
