Scanned, then parsed in memory
Your file is scanned for threats and parsed entirely in memory. The raw file is discarded the moment parsing finishes — it is never written to disk or to our database.
Costs recomputed from our verified registry
We recompute every cost from our verified model-price registry. We never trust the cost numbers in your CSV.
Never sent to any AI model
Your usage data is never sent to an LLM or any third party. The analysis is deterministic local computation — zero AI calls.
Anonymous and self-deleting
Running a Waste Check writes zero rows to our database. The computed summary lives in a temporary in-memory store and is deleted automatically after 30 minutes.

How Cromus handles your usage data — full disclosure
Which usage exports can I upload?
Waste Check accepts CSV usage exports from OpenAI and Anthropic. For persistent multi-provider tracking, sign up and use the Token Tracker inside your Cromus workspace.
Do I need an account to run a Waste Check?
No. You can upload an OpenAI or Anthropic CSV without signing in. The file is scanned and parsed in memory, and the temporary results are deleted automatically after 30 minutes.
How is my usage cost calculated?
Cromus recomputes estimated costs using the model prices in its verified registry rather than relying on any cost totals in the CSV. Estimates may differ from your provider's invoice.
Is my CSV sent to an AI model?
No. Waste Check uses deterministic processing and does not send your CSV or usage data to an AI model.
How do I track usage over time?
Sign up for a Cromus account to open the Token Tracker in your authenticated workspace. It supports OpenAI, Anthropic, Google AI Studio, and OpenRouter exports, and keeps your upload history in your account.
