Privacy Policy

Last updated: September 2026

Signal Technologies Ltd ("GetSignal", "we", "us"), a company registered in England and Wales (company number 17154561), with its registered office at 66 Paul Street, London, England, EC2A 4NA, provides GetSignal, a market intelligence mobile app for iOS and Android that lets you follow companies, fund managers, institutional investors, and members of Congress, and receive a personalized feed of their SEC filings, trades, and related market events, with optional push alerts. This Privacy Policy explains what we collect, how we use it, and the choices you have. It applies to the GetSignal mobile app and the getsignal.finance website (together, the "Service").

1. Information We Collect

  • Account information: Your email address and authentication identifiers, created and managed through Firebase Authentication (a Google service). Your password is handled and stored by Firebase. GetSignal never sees or stores your raw password.
  • Your follows and preferences: The companies, tickers, funds, and Congress members you follow; your notification rules and settings; and feed state such as which items you have read or hidden.
  • Notifications and device data: If you enable push notifications, we store a push token (via Expo) for your device, along with device type, operating system, and app version needed to deliver alerts.
  • Usage and diagnostics: IP address, device and app identifiers, app version, interactions within the app, timestamps, and error or crash diagnostics.
  • Advertising attribution: When the app first opens, it asks the platform how you found us. On iPhone, it asks Apple's AdServices framework for a short-lived token and sends it to us. We pass the token to Apple, which tells us whether the install came from an ad GetSignal ran on the App Store and, if it did, the campaign, ad group, keyword, ad and placement, the country or region, and when the ad was tapped or seen. On Android, it reads the install referrer that Google Play recorded for your install: the tag on the link you followed and, if you came to us from an ad we paid for, a Google click identifier. We store this with your app install identifier and, if you create an account, with your account. Neither Apple nor Google gives us your name, email address or advertising identifier, and none of this involves tracking you across other companies' apps or websites.
  • Subscription status: If you start a GetSignal Pro trial or subscription, our payments partner tells us whether your entitlement is active and when it expires. We never see or store your card details: Apple and Google take the payment and hold the payment method.
  • Communications: Any messages, feedback, or support requests you send us.

What we do NOT collect: GetSignal does not connect to your brokerage, and we do not collect or store your brokerage credentials, bank account numbers, card details, or your personal trading or portfolio holdings. Subscription payments are handled entirely by Apple and Google. The financial information shown in the app, including filings, insider transactions, institutional holdings, and congressional trades, is public market data about third parties (public companies, institutions, and public officials), not data about you.

2. How We Use Your Information

  • To build and serve your personalized, pre-loaded feed and entity profiles
  • To deliver push notifications according to the alert rules you configure
  • To create, authenticate, secure, and maintain your account
  • To diagnose technical issues, monitor performance, and improve the Service
  • To measure how well GetSignal's own advertising works, for example how many installs from an ad go on to use the app or create an account
  • To detect, prevent, and address fraud, abuse, and security incidents
  • To comply with legal obligations and enforce our Terms of Service

We do not use your information for third-party advertising, and we do not sell it.

3. Public Market Data

The filings, trades, holdings, ratings, and events presented in the Service are sourced from public records, including SEC EDGAR and congressional STOCK Act disclosures, and from third-party market data providers. This information concerns public companies, institutional investors, and public officials' statutory disclosures. It is not generated by, and does not describe, GetSignal's users. We present it for informational purposes only (see our Terms of Service) and are not the originator of this data.

4. How We Share Information

We do not sell, rent, or trade your personal data. We share data only with service providers that operate the Service on our behalf, and only as needed:

  • Google Firebase: account authentication
  • Google Ads: measurement of our own advertising on the website, as described in section 6
  • Neon: managed PostgreSQL database hosting
  • Cloudflare: application hosting, edge delivery, and security
  • Expo: push notification delivery
  • RevenueCat: subscription management, which tells us whether your GetSignal Pro entitlement is active
  • Apple App Store and Google Play: app distribution and, where applicable, crash reporting; on iPhone, Apple's AdServices service confirms which of our App Store ads, if any, led to an install

These providers are bound to protect your data and use it only to provide their service to us. We may also disclose data where required by law, subpoena, court order, or government request, or to protect the rights, safety, or property of GetSignal or others; and, in the event of a merger, acquisition, or sale of assets, your data may transfer as part of that transaction (we will notify you of any such change).

5. Push Notifications

Push notifications are optional. If you enable them, we store a device push token to deliver alerts that match the rules you set (event types, followed entities, and importance thresholds). You can disable notifications at any time from within the app or in your device's operating system settings.

6. Storage on Your Device, Cookies and Similar Technologies

The mobile app stores your authentication session and preferences locally on your device so the app loads quickly and keeps you signed in. The getsignal.finance website uses essential and functional cookies and local storage to maintain your session and remember preferences.

The website also runs Google's advertising tag, which sets a Google cookie so that we can measure our own advertising: when someone reaches the site from an ad we paid for and then taps through to the App Store or Google Play, Google tells us which ad it was. If you tap the Google Play badge, the Google click identifier is added to the Play link so that the install can be matched to the same ad. We turn personalised advertising off in that tag, so it is not used to build an advertising profile of you or to follow you around other websites, and we do not run remarketing. If you arrive from one of our own ads or campaign links, the website keeps the campaign you arrived on in your browser's session storage for that tab, so that the store link still carries it if you read a page or two first. It is not an identifier, it names the ad, and it is discarded when you close the tab. In the European Economic Area, the United Kingdom and Switzerland the tag is set to store nothing on your device unless and until we ask for your consent.

The website also keeps its own count of page visits, on our own servers and without a cookie: a random session number that lives in your browser's session storage for that tab and is discarded when you close it, the page you opened, the website that linked you here, the country Cloudflare reports for the request, and how long the page was open. If you arrived on one of our own ads or campaign links, that count also records the campaign tag on the link you followed: the source, medium and campaign name, and the advertising click identifier if the link carried one. We record the campaign tag and not the rest of the web address you arrived on, and we record it for one reason, so that we can tell which of our own advertising is worth paying for. It is not tied to your account, it is not shared with anyone, and it is not used to follow you to other websites. If we have marked a browser as ours for testing, by opening the site with ?nostats=1, that mark is kept in the browser's local storage so that our own visits can be left out of the count.

7. Data Security

We use industry standard safeguards, including encryption in transit (TLS/SSL), encrypted storage, and access controls, and we rely on the security programs of Firebase, Neon, and Cloudflare. No method of electronic transmission or storage is 100% secure, and we cannot guarantee absolute security. You are responsible for keeping your account credentials confidential.

8. Data Retention

We retain your personal data for as long as your account is active or as needed to provide the Service. If you delete your account, we will delete or anonymise your personal data within 30 days, except where we are required to retain it for legal, regulatory, or legitimate business purposes. Anonymised, aggregated data that cannot identify you may be retained.

9. International Data Transfers

Signal Technologies Ltd is based in the United Kingdom, and our service providers (including Firebase, Neon, and Cloudflare) process data in the United States and other jurisdictions. Where personal data is transferred outside the UK, we rely on appropriate safeguards (such as the UK International Data Transfer Agreement or equivalent measures). By using the Service, you consent to the transfer of your data to these jurisdictions, which may have different data protection laws than your country of residence.

10. Children's Privacy

GetSignal is intended for adults and is not directed to anyone under 18. We do not knowingly collect personal data from minors. If we learn we have collected data from a person under 18, we will delete it promptly. If you believe a minor has provided us data, please contact us.

11. Your Rights and Choices

Depending on your jurisdiction, you may have the right to:

  • Access the personal data we hold about you
  • Correct inaccurate or incomplete data
  • Delete your personal data
  • Export your data in a portable format
  • Object to or restrict certain processing
  • Withdraw consent where processing is based on consent

You can delete your account, and the personal data associated with it, from within the app; see how to delete your account. You can also exercise any of these rights by contacting us at [email protected]; we will respond within 30 days.

12. Changes to This Policy

We may update this Privacy Policy from time to time. We will communicate material changes via the app, email, or a prominent notice at least 14 days before they take effect. Your continued use of the Service after changes take effect constitutes acceptance.

13. Contact
