How InstaMinsta Tests Download Reliability
The repeatable checks behind our reliability reports, status statements, and product changes.
Testing principles
- Use public post links only; never provide credentials or attempt private-account access.
- Report the date, sample size, selection limits, tools, and observable results.
- Separate resolver success from playable-file success.
- Treat poster images, HTML errors, empty responses, and corrupt containers as failures.
- Do not claim universal quality, anonymity, uptime, or compatibility from a small sample.

Sample handling and privacy
Published reports describe aggregate observations and do not publish a permanent library of downloaded media. Test files are temporary QA artifacts. Reports avoid exposing private identifiers, credentials, cookies, or user-submitted URLs.
Operational telemetry records coarse events such as resolution outcome, source class, duration, download start, and completed byte count. It is not intended to record the Instagram URL or media contents.
Update and correction policy
A dated report remains a historical snapshot. We update its current-status note only after a repeatable test. Material corrections are recorded in the changelog. If a result cannot be reproduced, the page should say so rather than silently preserving the stronger claim.
