How does müll.io work & Privacy

müll.io bundles the collection data from various waste disposal services behind a unified interface – without you having to provide personal data.

How does müll.io work?

The platform müll.io determines the appropriate disposal provider for a given address. Since each municipality and each disposal service uses its own systems, each provider is integrated separately.

Capture address: You enter an address or a third-party system transmits it via API/MCP.
Determine provider: müll.io searches for the responsible disposal service based on the address.
Retrieve pickup dates: If a provider could be assigned, the address is passed to their system to retrieve the pickup dates.
Cache result: The response is cached for a few days so that repeated queries are answered quickly and without load for the provider.

Important: The address leaves müll.io exclusively in the direction of the responsible provider – and only when there is no valid cache entry stored there.

Which data is stored?

Privacy is not an afterthought at müll.io, but a fundamental principle. In concrete terms:

No plain-text addresses: The address is processed using a hash method. The cache contains no readable record, only a hash value.
No logs with address data: Neither request logs nor statistics contain the user's address.
No personal profiling: No user profiles are created and no data is shared with third parties – with the exception of the mandatory transfer to the respective disposal provider required for the query.

Why do we cache?

The cache has two functions: it makes müll.io fast and simultaneously protects the disposal services' systems from unnecessary load. An address is therefore only forwarded to a provider again when the stored entry has expired.
