Privacy Policy for Thrumm

Last Updated: November 4, 2026

Introduction

Thank you for using Thrumm ("the App"). This Privacy Policy is designed to help you understand how we handle information when you use the App. The short version: the App has no accounts, no analytics, and no server of ours. The App sends nothing to us. Your library stays on your devices and in your own iCloud account.

Information Collection

The App does not collect any personal information from users. We do not:

• Collect your name, email address, or other contact information
• Track your location
• Monitor your device usage or use analytics tools
• Send your listening history, your statistics, or any user identifier to any service other than your own iCloud account
• Use cookies or similar tracking technologies
• Sell any information, or share it with third parties except as this policy describes

The App has no sign-in and no user account of its own. We operate no server that receives data from the App.

Information Stored on Your Device

The App stores the following on your device, so that it can work as a podcast player:

• Your subscriptions, your play queue, your playback positions, and which episodes you finished
• Downloaded episode audio files, stored exactly as the publisher served them
• Transcripts, ad markers, and chapters that the App generates for episodes you play or scan
• Your settings, your corrections to detected ads, and your custom skip rules
• Statistics such as the count of ads skipped and the time saved
• Whether Thrumm+ is active
• A cache of show artwork

None of this leaves your device except as the next sections describe. Deleting the App removes all of it from that device. Deleting the App does not remove the copy in your iCloud account.

iCloud Sync

When you are signed in to iCloud, the App syncs some of this information between your devices through your own iCloud account. With no iCloud account, nothing syncs, and the App works the same in every other way.

These items sync:

• Your subscriptions and your settings for each show
• Your playback positions and which episodes you finished
• A record of each ad skip and of the time that Skip Silence saved, with the date, the show, and the episode. Your statistics come from these records.
• Your custom skip rules

These items stay on the device where the App made them: downloads, transcripts, ad markers, your corrections to detected ads, generated chapters, your play queue, and your other settings.

The App keeps synced data in your private iCloud database. By default, only you can access this database, and we cannot see its content. Apple encrypts the data in transit and on its servers, and the data counts toward your iCloud storage. Apple's privacy policy applies. Apple explains how to manage your iCloud storage.

Ad Detection

The App finds ads by transcribing episode audio and analyzing the transcript. Transcription runs on your device using Apple's speech frameworks. The App also analyzes the sound of an episode on your device. Transcript analysis runs using Apple Foundation Models, either on your device or on Apple's Private Cloud Compute. The App also uses these models to create chapters.

When analysis runs on Private Cloud Compute, the App sends Apple's service the transcript text of the segment being analyzed. The request also carries the show title, the episode title, and part of the episode description. For ad detection, it also carries your custom skip rules that apply to the episode. Apple designs Private Cloud Compute so that request data is used only to fulfill the request, is not retained after the response, and is not accessible to Apple. No audio file is ever sent anywhere. The App sends no transcript to any service other than these models. Detection results are never shared between users.

Network Requests

Like every podcast app, the App makes network requests to do its job. Each server can see your IP address, as with any internet request. These requests carry no user identifier of ours and no listening history:

• Podcast publishers. The App fetches RSS feeds and downloads episode audio, chapter files, and artwork directly from the servers each publisher uses. Those servers see the request in the same way they see a request from any other podcast app, and their own privacy policies apply.
• PodcastIndex. Show search, browse lists, and feed lookup use the PodcastIndex API. Each request carries the App's API key, which is the same for every user.
  • A search request carries the text you typed.
  • A browse request carries a result cap, a language code, and sometimes category names. The App can choose those categories from the genres of your subscriptions, but the request names no show.
  • A feed lookup carries a feed address, an iTunes ID from a Top list, or a PodcastIndex show ID. The App sends a feed address when you add a show by its address, and it sends the address of each show in a subscription file that you import. A private feed address can contain a personal token from its publisher, and the App sends the address unchanged.
  • If a show has no usable feed address, the App requests its episodes from PodcastIndex by show ID.
• Apple charts. The Top lists come from Apple's podcast charts. A request carries a store code, a genre ID, and a result cap.
• Links you open. Show notes can contain links. The App makes no request to a linked site until you open the link.

Purchases

Thrumm+ and tips are App Store purchases. Apple processes the payment, and Apple's terms and privacy policy apply. The App never receives your payment details, and it keeps no purchase history. It stores only whether Thrumm+ is active, which it reads from the App Store. The App adds no identifier of its own to a purchase.

Sharing You Choose

The App can share three things when you ask it to: transcript lines you select, an image of your overall statistics, and an export file of your subscriptions. You choose the destination in the system share sheet. The destination receives what you share, and its own privacy policy applies.

Device Motion

The Stats page and the Milestones page use the motion sensors of your device to move a light effect. The App reads the sensors only while the page is on screen. It does not store or send this information.

Third-Party Services

The App uses no third-party analytics, advertising, or crash-reporting SDKs. The App never shows or inserts an ad of its own. The only outside services it contacts are podcast publishers, PodcastIndex, and Apple (iCloud, Private Cloud Compute, the App Store, and the podcast charts), as described above.

Children

The App does not collect personal information from anyone, including children under 13.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page. We recommend that you review this Privacy Policy periodically for any changes.
