Before writing we say, in a number, what each format will lose. After writing we read the result back and check it.

We do not store your data. The file is deleted as soon as it is no longer needed for processing. What we read — our model of the file — is deleted once the processing period ends (24 h). The final file exists only with you: we assemble it from the model at the moment of download, and keep it available for download no longer than 24 h. What stays with us afterwards is anonymized data only — statistics and the outcome of processing, counters, the data's schema — tied neither to the source file nor to you. Neither the source nor anything derived from it is passed to anyone. Among that anonymized data we also keep a salted fingerprint of your dataset's layer names, used only to notice when unrelated files share the same schema.
