Privacy by architecture

Your client files should not become our database.

Local tools run inside your browser. The spreadsheet or JSON file you select is held in temporary browser memory and is not uploaded to CntrlLedger.

Professional by design

Useful enough for daily work. Honest enough for professional review.

Founder Hirdaypal Lamba

Building practical, privacy-first tools for India’s accounting community.

✓

Visible assumptions

Thresholds, tolerances, dates and rates can be reviewed instead of hiding inside a formula.

✓

Directionally clear differences

Reconciliations label the source and sign so reviewers know what a variance means.

✓

Working-paper exports

Reports include source data, exception tabs, summaries and read-me notes.

✓

No false certainty

Statistical flags and tax calculations remain review aids, not conclusions or filings.

Common questions

Before you begin.

Is CntrlLedger really free?

The browser tools are available free during beta. AI use has a small daily limit to control processing cost.

Are uploaded client files stored?

Local-tool files stay in temporary browser memory. Invoice AI sends a document to Google Gemini only after you explicitly consent.

Can I file GST returns from here?

No. CntrlLedger prepares review workings and exports. It does not log into the GST portal or submit a return.

Will this replace professional judgement?

No. The tools reduce repetitive preparation work. A qualified reviewer remains responsible for source records, current law and the final filing or entry.
