Privacy Policy
Last updated: 12 July 2026
This Privacy Policy explains how Signalyst ("Signalyst", "we", "us")
collects, uses, and protects your information when you use the Signalyst mobile
application (the "App") and related services. By using the App you agree to this Policy.
Signalyst provides AI-assisted, educational stock analysis and buy/sell
signals. It is
not financial, investment, or trading advice. See our
Terms of Service.
1. Information we collect
- Account information — your email address, an optional display name,
and a securely hashed password. If you sign in with Google, we receive your email address,
name, and Google account identifier via Google/Firebase Authentication.
- Subscription information — when you start a trial or subscribe, Google
Play Billing provides us a purchase token, product identifier, and subscription status. We
do not receive or store your card or payment details; all payments are
processed by Google Play.
- Content you create — your watchlist, portfolio holdings and
transactions you enter, the markets/exchanges you follow, and your notification
preferences.
- Device & notification data — a push-notification (FCM) token so we
can send you alerts, and your approximate country/region (derived from your IP address) to
show relevant markets.
- Optional integrations — if you connect Telegram, we store your Telegram
chat identifier so we can deliver alerts there.
- Technical logs — IP address and basic request logs, used for security,
rate-limiting, and abuse prevention.
2. How we use your information
- To create and secure your account and keep you signed in.
- To provide the App's features — signals, watchlist, portfolio tracking, your daily
briefing, news, and alerts.
- To process and verify your subscription and free trial through Google Play.
- To send transactional emails (e.g. email verification, password reset) and, if enabled,
push/Telegram alerts.
- To maintain security, prevent fraud and abuse, and comply with legal obligations.
3. How we share information
We do not sell your personal information. We share data only with service
providers that help us operate the App:
- Google — Play Billing (subscriptions), Firebase Authentication (Google
Sign-In), and Firebase Cloud Messaging (push notifications).
- Hosting & infrastructure — our backend runs on DigitalOcean and is
served through Cloudflare.
- Market-data providers — we retrieve market data from third-party data
providers; this does not involve sharing your personal information.
We may also disclose information if required by law or to protect our rights and users.
4. Data retention
We keep your account data for as long as your account is active. When you delete your
account, we delete your personal data as described below, except where we must retain limited
records to meet legal, tax, or fraud-prevention obligations.
5. Your rights & deleting your data
You can access and update your information in the App. You can delete your account and
associated personal data at any time from Settings → Delete account, or by
following the instructions on our Data Deletion page. Deleting your
account does not automatically cancel a Google Play subscription — manage that in Google Play.
6. Security
We protect data in transit with HTTPS/TLS, store passwords only as salted hashes, and
restrict access to production systems. No method of transmission or storage is 100% secure, but
we work to protect your information.
7. Children
Signalyst is intended for adults (18+) and is not directed to children. We do not knowingly
collect personal information from children.
8. International users
Your information may be processed on servers located outside your country. By using the App
you consent to this transfer and processing.
9. Changes to this Policy
We may update this Policy from time to time. Material changes will be reflected by updating
the "Last updated" date above and, where appropriate, an in-app notice.
