The tools log nothing
The SPD decoder and the capacity calculator run entirely in your browser. The numbers and answers you enter — your compensation, deferrals, and plan answers — are never sent to a server and never stored. Closing the tab discards them.
What we do collect
We use privacy-respecting page-view analytics to understand which pages are useful. This records anonymized usage (such as which page was viewed) but not the contents of any calculator input. There are no advertising or retargeting cookies on this site.
Consent
On your first visit you can allow or decline analytics. We default to a consent posture that denies advertising signals; analytics can be declined at any time. MegaBackdoorCheck does not sell personal information.
Third parties
We do not embed third-party trackers beyond the analytics described above. If sponsor or advertising placements are ever added, this notice will be updated before they go live, and any such placement will be clearly labeled.
