Privacy Policy
Deltabrief collects nothing about you. There is no account, no sign-up, no analytics, no advertising and no tracking of any kind. What you read, what you save and how you set the app up never leaves your iPhone.
This policy explains that in full, including the few places where your device does talk to a server, and what those servers can see.
What we collect
Nothing. Deltabrief has no servers of its own, no account system and no analytics or crash-reporting service. We do not receive your name, email address, device identifier, location, contacts, reading history or usage statistics — because none of it is ever sent anywhere.
The app contains no third-party SDKs. It does not use the Advertising Identifier (IDFA) and does not ask for permission to track you across other apps or websites.
What stays on your device
Deltabrief stores the following in the app's private storage on your iPhone:
- Briefs you have downloaded, so the archive still reads without a signal
- Bookmarks and which issues you have opened
- Your settings — refresh interval, offline preference, notification preference, reading text size, speech rate and chosen voices
- A small snapshot of the newest issues, written to a shared app group container so the Home Screen widget can display them
This data is readable only by Deltabrief and its widget. It is included in your device backup if you back your iPhone up to iCloud or a computer, under Apple's protections rather than ours. Deleting the app removes all of it.
Where the briefs come from
To show you new issues, your device requests publicly published content directly from:
aisengtech.com— the site the briefs are published onapi.github.comandraw.githubusercontent.com— where the same posts are stored
These are ordinary, anonymous web requests for public files. They carry no account, no identifier and nothing about you. As with any web request, the server on the other end necessarily sees the connecting IP address and standard request headers, and handles them under its own privacy policy — see GitHub's privacy statement. We receive no record of these requests.
Permissions the app may ask for
Notifications
Optional, and off until you turn it on. Deltabrief asks for notification permission only at the moment you enable “notify me about new briefs” in Settings — never at launch. Notifications are created locally on your device when the app finds new issues. There is no push server, so nothing about you is registered anywhere to deliver them.
Background activity
The app may refresh in the background and continues playing spoken audio when it is not on screen. Both happen on your device, and neither reports anything.
Reading aloud
Spoken briefs use the speech synthesis built into iOS. The text is handed to the operating system on your device and is governed by Apple's own privacy policy. Deltabrief does not record audio, does not use the microphone, and has no microphone permission.
Search and Siri
Briefs are indexed in Spotlight so you can find them from the Home Screen. That index is maintained by iOS on your device. The app's Siri shortcuts are handled on the device as well. Apple, not Deltabrief, determines what these system features do with the information — see Apple's privacy policy for Siri and Search.
Payment
Deltabrief is a paid app with no in-app purchases and no subscription. Your purchase is handled entirely by Apple through the App Store. We never see your payment details, card number or billing address, and receive only anonymous, aggregated sales figures from Apple.
Children
Deltabrief is a technology news reader intended for a general audience. It is not directed at children under 13, and since it collects no data, it collects no data from children.
Your rights
Regulations such as the GDPR, the CCPA and Singapore's PDPA give you rights to access, correct, export or delete the personal data a company holds about you. Deltabrief holds none, so there is nothing for us to disclose, correct or erase. The data on your device is yours already: delete the app and it is gone. There is nothing to opt out of, because nothing is collected, sold or shared.
Changes to this policy
If a future version of Deltabrief changes what it does with data, this page will be updated before that version is released, and the date at the top will change. Material changes will also be noted in the app's release notes.
