Open the tool → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Approval start date
- 2026-06-01
- Approval end date
- 2026-11-30
- Units or visits approved
- 2
- Units or visits used so far
- 1
- Units given at each administration
- 1
- Days between administrations
- 56
- Next scheduled administration
- 2026-07-20
- Days ahead to submit the renewal
- 14 days
Result: The approval ends November 30, 2026, but the 1 unit left cover 1 more administration at 1 per administration every 56 days, so the administration on September 14, 2026 needs a new approval. Submit the renewal by August 31, 2026.
