Terms and notices

Terms of use

Glidechart is offered under the standard terms of the store you get it from, and under no other terms of ours:

• on the App Store, Apple’s Licensed Application End User License Agreement;
• on Google Play, the Google Play Terms of Service.

Reference only

Reference tool only — verify against manufacturer specs and site conditions before charging.

Glidechart gives readings. It does not judge a charge, and it does not replace the equipment manufacturer’s data or a technician’s judgement.
