Four editions. Save stories and read offline.
Enable notifications in the iPhone app.
Four notifications a day, no more. Just the four signals you need throughout the day.
Your data, explained.
This policy covers the Signal10 website and iOS app. Signal10 is operated by Facundo Barrera in Luxembourg. We do not sell reader data or use advertising trackers or third-party analytics SDKs. Updated 26 October 2026.
Reading and device storage
No account is required to read. The iOS app stores downloaded editions, opened briefs and saved stories on your device for offline reading. Your saved list is not uploaded to Signal10. You can remove saved stories in the app; deleting the app removes its local app data, subject to any device backups you manage with Apple.
Requests and operational logs
Loading editions, searching and opening briefs sends requests to Signal10. Our server and infrastructure may log IP addresses, requested paths, search terms, article identifiers, response codes and request times for service operation, security and troubleshooting. We do not use these records to build advertising profiles. The application does not currently enforce an automatic expiration period for infrastructure logs; retention also depends on hosting, log rotation and backups.
Optional push notifications
When you allow notifications, the app sends its Expo push token and app/version label to its own backend over HTTPS. We store that token, registration and last-seen times, active status, and delivery tickets/error codes to operate and troubleshoot notifications. The token identifies an app installation; it is not linked to a reading list, Photos library or newsletter subscription. Notification payloads and the token are processed by Expo Push Service and Apple Push Notification service (APNs). We do not use this information for advertising or cross-app tracking. You can turn notifications off in iOS Settings without losing access to the app. Turning them off does not automatically erase the server record. Invalid tokens are deactivated when the delivery provider reports them. Push records and delivery history currently have no automatic expiry; to request deletion, contact [email protected]. We may need information sufficient to locate and verify the installation; backups may retain earlier copies until replaced.
Optional newsletter
Subscribing sends your email address to Signal10. We store the address, subscription state, timestamps and random confirmation and unsubscribe tokens. We use them to confirm your request and deliver the newsletter through our configured email provider. After double opt-in, the operator receives a notification containing the subscribed address. Newsletter consent is optional and does not affect access to the app.
Unsubscribe, retention and deletion
Every newsletter includes an unsubscribe link. Unsubscribing stops future delivery immediately, but does not delete the subscription record: the email and inactive status remain in our database. Pending and inactive records currently have no automatic expiry. To request deletion of your subscription data, email [email protected] from the subscribed address. We may need to verify the request; backups may retain earlier copies until replaced under their retention settings.
Service providers and external sources
Cloudflare and hosting infrastructure process technical request data to deliver and protect the service. Our email provider processes newsletter delivery data. Article images can load directly from publishers or their image hosts, which receive technical connection data such as your IP address. Opening an original source, an external link or a newsletter preview connects you to that website, whose privacy policy applies. Device backups and TestFlight are managed by Apple under its own policies.
AI and the news archive
Signal Briefs are generated from news-source content on our hosted infrastructure. Newsletter addresses and saved reading lists are not sent to the model. Article metadata, rankings and generated briefs are retained in the news archive. The archive is separate from personal subscription records.
Your choices and contact
For access, correction, deletion, objection or other requests concerning your personal data, contact Facundo Barrera at [email protected]. You can withdraw newsletter consent through the unsubscribe link. Where applicable, you may complain to Luxembourg’s data protection authority, the CNPD.
Changes
We will update this page when our data practices change. The date above identifies the current version. Material changes to the purposes for which newsletter consent was given will require appropriate notice and, where necessary, renewed consent.
