Product handbook

What the app can do. And what it cannot.

Data sources, methods, pricing and limits, without the marketing language. For the short version, go back to the home page.

The work happens on your Mac

You sign in to the accounts you manage. Sonventory reads whatever the platforms give it and writes the results to your Documents folder. No Sonventory account is needed for that.

You connect your channels

You sign in to YouTube, TikTok and Instagram in your system browser, through their official interfaces. The app receives a read-only token. Your password stays with the platform, and your video files are not uploaded to Sonventory. Audio signatures are sent to Apple for recognition.

Audio preparation runs locally

Sonventory prepares short audio excerpts on your Mac. ShazamKit creates signatures locally and sends those signatures to Apple’s music catalogue for matching. No other recognition service is involved.

You enter the reference

You add your licence reference to a detected recording. Sonventory stores the text with a timestamp. It never checks it, neither the reference nor the contract behind it.

Per video

What the app records for each video

Some of it comes from the official platform interfaces, the rest Sonventory works out on your Mac. If a source leaves a field empty, it says so.

Platform & video linkThe source link sits next to the record.
Title, artist, album, ISRCThe metadata for the detected recording, linked on to Apple Music, Shazam and MusicBrainz.
Detected time windowWhich part of the video triggered the match.
Match scoreA technical value from the recognition, not a legal probability.
Reach and engagementViews, likes, comments, shares, saves and, where available, reach rather than only views.
Retention curve and derived figuresHook, hold, completion and rewatch rate, half-life of attention, and the steepest drop with its timestamp.
Comments with sentimentFrom YouTube and Instagram, with a link to the individual comment where the platform publishes one.
Documentation state & timeThe app stores the state and the time of the latest analysis.
YouTube & Shorts TikTok Instagram & Reels

Five states show what still needs attention

The states describe the condition of your records. They do not say whether a use of music was legally permitted.

The recognition's match score is a technical value. It describes how confident the match is technically, never a legal probability.
StateMeaningYour next step
No recording detected Automatic recognition found no commercially released recording. None. Music may still be present and simply not have been recognised.
Reference on file Your licence reference for the detected recording is on file, stored exactly as entered. None. The entry is complete.
Your reference pending A commercially released recording was detected; a reference is still missing. Add the reference if you hold a matching licence.
Platform notice The platform said something about the post itself. Quoted with its date, not interpreted. Read the statement and assess it internally.
Review incomplete Part of the video was not analysed; the entry has gaps. Run the analysis again.

Why Sonventory uses medians

One viral post drags a channel average out of shape. The median holds. Every result also states the range the underlying data actually covers.

Median, not meanThe median is the value in the middle of the row. An outlier at the top end does not move it.
Track effect with a rangeInstead of "+34%" it says "+34%, but anywhere between −5% and +80%". Where nothing is established, it says so.
Concentration made visibleHow much of the channel rests on how few posts, written out as "the top 20% carry X%".
The whole distributionA histogram with a median line shows how widely the values spread.
The platforms' own counting rulesViews, plays and reach use different definitions across platforms and formats. Sonventory preserves the source and distinguishes reported values from derived estimates.
Sentiment with abstentionUncertain comments count as "no clear tone" and are excluded from the percentage.

Three platforms, three different sets of data

YouTube, TikTok and Instagram do not expose the same fields. This table shows what is currently available. In the app, the source sits next to each value.

Availability depends on approved interfaces, account eligibility and permissions. Checked 9 September 2026. See TikTok portability and Google portability eligibility.

What the region changes

Metrics depend on the platform, account type and permissions. On TikTok and YouTube, Sonventory reaches the video files themselves only through their data portability features, and music can be identified only from those files. Both providers currently list the EEA and the United Kingdom as eligible regions. Access also depends on platform approval, account eligibility, permissions and the files supplied. Outside those regions the connection still works, but music recognition does not run there. The app states this on the affected connection.

Where each type of data goes

Sonventory has no registration, no user database and no server holding your content. The full account is in the privacy policy.

DataWhere it lives
Videos, metrics, comments, references On your Mac, in the app's folder. You can delete them there like any other file.
Platform access tokens In your login keychain. You can revoke access at any time with the platform concerned.
Sentiment analysis of comments Entirely on your Mac. The comment text stays on the device.
Audio signatures for recognition Go to Apple's music catalogue to be matched. Sonventory sends the signature. The video file stays on your Mac.
Downloaded video files Only temporarily on your Mac, until recognition is done, then they are deleted.
At Sonventory None of it. We run only a small relay service for the sign-in flow at TikTok and Instagram, because their process requires it. It stores none of your content.

What it costs

Planned euro prices. The price, currency and applicable taxes displayed by the Mac App Store at purchase govern.
ItemHow it works
Sonventory Pro, monthly €19 per month, cancellable monthly.
Sonventory Pro, yearly €179 per year, about 21% less than twelve single months.
Feature set Both plans include the same features. There is no channel or video limit.
Demo mode The demo archive runs without a subscription. It holds a fictional agency with 3 channels and 2,000 generated demo videos.
Billing On purchase in the Mac App Store through your Apple Account. Invoicing, renewal and cancellation run there; Apple's terms govern.
Cancellation In the subscription settings of your Apple Account, at any time with effect from the end of the current period.
Restoring An existing subscription can be restored in the app on your devices.
After the subscription ends Your data stays on your Mac. Access to the analysis ends, and the files stay in your Documents folder.

Sonventory does not verify rights

Sonventory shows the result of automatic recognition, the match score and the date. Whether the use is licensed depends on your contracts and the applicable law. The app does not have that information.

That is deliberate. An automated legal review of an individual case would be a legal service under section 2 RDG, which this tool is not allowed to offer. So there are no risk levels in the app, no assessment of warning-letter exposure, and no recommendation to change or delete a post.

What the app delivers is documentation that stands up as evidence. For the legal assessment, turn to your legal department, your licensing office or a lawyer.

Technical limits

Automatic recognition is not exhaustive

Audio that is short, quiet, buried under speech, pitched, sped up, slowed down or re-performed is often not recognised, or recognised wrongly. "No recording detected" is therefore no evidence that a video contains no music and no third-party rights.

The music catalogue is limited

Only what exists in the music catalogue can be recognised. Production music, library tracks, original compositions and regional releases are frequently missing from it. The artist, album and label details are likewise catalogue entries as of the time of the query. Who holds the rights is not stated there.

What is possible depends on the platforms

Which videos, which metrics and which comments are reachable at all is decided by YouTube, TikTok and Instagram through their interfaces, including quotas, regional restrictions and changes without notice. If a platform changes what it offers, the feature set changes with it.

Records have a date

A record describes the state at the moment it was collected, and both posts and metrics keep moving after that. So every entry carries a date.

Frequently asked

Questions people ask before buying

What exactly does Sonventory do?

Sonventory analyses the channels you manage. That includes reach, retention, audience, content and comments. At the same time, the app records identified music with a time window, score, your reference and the date.

Do you check licences or copyright?

No. Neither the app nor we examine copyright, neighbouring rights, licence terms, platform licences or chains of title. The references you enter yourself are stored, not validated. The app is not able to do that and says so openly. More on this

Will I get a statement about my legal exposure?

No, and that is a deliberate decision. A risk assessment of an individual case would be a legal assessment. Sonventory shows instead where your documentation is complete and where something is still missing.

Do you need my credentials or my files?

No. Sign-in happens directly with the platform in your system browser; the app never sees your password. It receives a read-only access token, stored in your keychain. Video files are not uploaded to Sonventory. Recognition signatures go to Apple, and sign-in exchanges for TikTok and Instagram pass through our relay.

Can I analyse channels I do not own?

No. Sonventory receives data only after someone signs in to the account and grants read access. Without that access, the app cannot read the channel.

Can we use it as an agency with several clients?

Yes. The app has no fixed channel limit. You can analyse one client channel or the full portfolio. Your clients must appoint you and allow access to their accounts.

What if a track was matched incorrectly?

Every recognition carries its match score and the time window that triggered it, and can be listened back to through the link to the video. You can have a video analysed again. On TikTok there is the added point that the platform names a sound for the post itself. The app carries both statements side by side and flags it when they disagree.

How long does the first analysis take?

It depends on channel size and platform. A large archive can keep the first run busy for several hours. Later runs are quick.

Does the app run on iPhone, iPad or Windows?

No. Sonventory is a Mac app for macOS 14 or newer, on Apple Silicon and Intel. Other platforms are not currently planned.

What languages is the app available in?

German and English. By default the app follows your system language, and you can change it in settings. Numbers, percentages, dates and currencies follow the chosen language too.

May I pass the exports on?

Yes, it is your data. The methodology note sits deliberately inside the export itself, as comment lines in the CSV and as its own field in the JSON, so that a figure passed on keeps the caveat that applies to it. Please do not present an export as a licensing or legal opinion; it is not one.

Start with the demo archive.

Request access, open the app and start the demo archive: three fictional channels, 2,000 generated demo videos, every view open. You need Sonventory Pro only when real accounts come in.
