Add clear rewards data and clear payment data

[NejcZdovc]

User should be able to remove rewards data (auto contribute, donation, tipping) and remove payment data (previous payments). This should delete the data on disk.

From browser laptop

Marking this as p3 and privacy related because currently there is no way to delete browsing history associated with rewards unless the user deletes the files on disk. if rewards is enabled, browsing history is logged to publisher_info_db. @NejcZdovc please correct me if i'm wrong.

I think the right solution would be to extend brave://settings/clearBrowserData to include controls for Brave Rewards.

For the simply view, we should add a "Brave Rewards data" item which removes all attention info created from the indicated time period.

On the advanced tab, we should add a couple of items.

• "Brave Rewards auto-contribute list" should remove attention history and auto-contribute items for the applicable time period.
• "Brave Rewards contribution history" should remove records of tips and contributions from the time period, replacing them with "private contribution" or something to that effect.

@mandar-brave @NejcZdovc Could someone on the Rewards team indicate whether there are any other ways that information equivalent to browsing-history might be stored?

[jasonrsadler]

What is defined as "applicable time period"? Currently we store auto-contribute information based on month and year. The options available when clearing data are "last hour", "last 24 hours", "last 7 days", and "last 4 weeks". How should we handle clearing data based on what is chosen?

@jasonrsadler Are you saying that we have no way of knowing what auto-contribute info was added in the last hour, the last 24 hours, or last 7 days?

[jasonrsadler]

Correct. @NejcZdovc to confirm but I believe we are only storing the month and the year.

[NejcZdovc]

@tomlowenthal that is correct we accumulate time per month and not per visit

[tildelowengrimm]

Sounds like we'll need to change that in order to be able to support deletion.

[diracdeltas]

Personally I would be happy if someone just added an option for "Clear Brave rewards and payment data since the beginning of time".

Having time intervals can be a follow-up but I don't think it's strictly necessary (we didn't have this in b-l)

[NejcZdovc]

I think we shouldn't change it. We should adjust place where we have clear like @diracdeltas said
