Question 1

Do I need a special SoundCloud account to use SoundCron?

Accepted Answer

No — any SoundCloud account works. Just click 'Login with SoundCloud' and authorize the app. Your regular SoundCloud credentials are used; we never see your password.

Question 2

What data does SoundCron store about me?

Accepted Answer

We store your SoundCloud user ID, display name, and your OAuth access and refresh tokens (encrypted at rest using AES-256-GCM — never in plaintext). We also cache classification results per track: track ID, genre, sub-genre, and a confidence score. If you subscribe to Pro, your email is collected by our payment processor Polar at checkout. See our Privacy Policy for the full picture.

Question 3

Is my audio uploaded or stored anywhere?

Accepted Answer

No. SoundCron never downloads, processes, or stores audio files. Only track metadata — title, artist name, and the genre tags already present on SoundCloud — is sent to the AI for classification. Your music stays on SoundCloud.

Question 4

How does the classification work?

Accepted Answer

When you run a sort, SoundCron fetches the metadata for each track in your playlist and sends it to an AI model. The model maps each track to one of our 40+ sub-genres. Results are cached per track, so re-sorting the same playlist is fast — already-classified tracks skip the AI call entirely.

Question 5

What is the "(Other)" playlist?

Accepted Answer

When the AI's confidence in a specific sub-genre is low, the track lands in a "<Genre> (Other)" playlist instead of (or in addition to) a specific sub-genre. This happens for tracks with vague or missing metadata. Adding better genre tags on SoundCloud and re-running the sort may move the track into the right sub-genre.

Question 6

What is included in the free tier?

Accepted Answer

Free users can run up to 5 sort jobs per day — triggering sorts manually by clicking 'Sync now' or 'Sync all'. Scheduled auto-sync (automatic periodic re-sorting on a cron) is a Pro feature.

Question 7

What does Pro include?

Accepted Answer

Pro gives you up to 500 sort jobs per day and the ability to create scheduled sync tasks — set a cron expression and SoundCron will automatically re-sort your playlists at that interval, keeping them tidy as you add new tracks. Pro is €3.99/month or €29/year (billed via Polar).

Question 8

How do I cancel my Pro subscription?

Accepted Answer

Click "Manage plan" in the app header. This opens the Polar self-serve billing portal where you can cancel at any time. You retain Pro access until the end of your current billing period. Partial-period refunds are not issued.

Question 9

How do I delete my account and data?

Accepted Answer

Email contact@soundcron.com with your request. We will delete all data associated with your account — OAuth tokens, track classifications, and any stored account metadata — within 30 days. Billing records held by Polar follow their own retention policy.

Question 10

What happens if SoundCloud is down?

Accepted Answer

Sort jobs that fail due to a SoundCloud API outage are marked as failed and can be retried manually. Scheduled sync tasks will skip a tick during an outage and resume normally at the next scheduled time. SoundCron has no control over SoundCloud's availability.
