# Unlimited history and full data sovereignty

Social networks are not an archive. Facebook deletes older data after two years, so comparing this season with the one before last often leaves you with nothing to draw on.

gas backs your data up as it goes and never deletes it. You pick the period on every page that shows data, either from presets or precisely from day to day. You also choose the interval the figures are totalled over, and every value carries a comparison with the previous period. Comparing two seasons stops being an afternoon project and becomes two clicks.

## The data stays yours

Your history is backed up and does not vanish when the platforms shorten theirs.

## Periods on your terms

Preset ranges as well as a custom selection from date to date.

## Comparison next to the number

Every value shows how it stands against the previous period.
