The Gricean Maxims are:
Maxim of Quantity: a contribution should be as informative as necessary for the exchange.
Maxim of quality: do not say what you believe to be false or something of which you lack adequate evidence.
Maxim of relation: provide only relevant information.

The first two sentences infringe the Maxim of Quantity because the hedges reflect a lack of detail in the information provided, meaning that information necessary for the exchange is missing.
The third sentence infringes the Maxim of quality because an assumption is information based on no evidence.
