AI coaching app Intervals Pro closed on Oct. 12, saying Garmin data will no longer be available through Intervals.icu. Gadgets & Wearables ties it to Garmin developer terms that Intervals.icu's developer flagged on Oct. 9. On Oct. 14 he said the third-party sharing requirements are not new.

What is confirmed

  • Intervals Pro: its own notice says billing has stopped, unused prepaid time is refunded automatically, and users can download their conversations until Oct. 19.
  • The Intervals.icu post: developer David wrote on the forum on Oct. 9 that Garmin's terms had been updated, that Intervals.icu got no announcement, and that it would likely have to block Garmin data in its API.
  • Garmin's public agreement: clause 5.2(o) bars "developing a Licensee application programming interface to provide End User Data to third-party websites, software applications, platforms, services, or products that have not been approved by Garmin in writing." The wording is identical in Garmin's 2023 and 2026 PDFs.

What is claimed or still open

David said on Oct. 9 that he had seen the revised terms only in Garmin's developer portal. Whether that version differs from the public PDF is unclear. No public Garmin statement has surfaced, so what is known of its position comes from David's account of his calls.

On Oct. 14 he wrote that Garmin told him the requirements are not new, the revisions are part of a planned reopening of its Connect developer program, and an easier path is coming for individuals and apps. He gave no details or dates. On Oct. 12 he had speculated that a block would probably cover Garmin-sourced activities, FIT files, streams, wellness data and history, and that nothing was final.

What it means for Garmin owners

Gadgets & Wearables reports that Garmin activities still sync into Intervals.icu, and that the open question is what happens when a platform passes that data to another app. For an Intervals.icu user, the loss David describes is in the API: apps that build on Intervals.icu data, such as Intervals Pro, may lose Garmin-sourced data, which he said on Oct. 9 Intervals.icu would likely have to block.

On Oct. 12 David said the limit, as he understands it, applies to data received through Garmin's API, including history that came in that way. He said files you upload yourself, even if a Garmin recorded them, are likely fine (Oct. 9).

If an app you use goes quiet

  • Download your history and any plans from the app now, while it still runs.
  • Export your activities from Garmin Connect as FIT files and keep them. David expects files you upload yourself to be fine; data an app pulls through Garmin's API is what is in question.
  • Check where the app gets its data. If it reads from Intervals.icu rather than Garmin directly, it is the exposed kind.
  • Watch the app's own notices and the Intervals.icu forum thread for changes.
  • Uploading your own FIT files to a service is the fallback David expects to stay fine, with more effort.

Why it matters

A free link between your watch and a smaller analysis or coaching app may depend on a third party's permission, not on your own Garmin account. The trade-off is convenience: you may need to export and upload files by hand, or use only apps Garmin has approved. Garmin's reopening plans could ease that, but none are published yet.
