PerfectPower App Privacy Policy
- Application developer: David METTEY
- Person to contact on privacy issues: David METTEY, by email via the application (SETUP page, Contact button)
- The one and only sensitive and personal user data accessed by the PerfectPower application is the GPS position, and it uses this data ONLY to perform the functions for which it was developed: the measurement of the standardized engine power, the accelerations standing and flying start, the braking, and the maximum speed of your car, the calculation of the gearbox ratios of this one by rev calibration, the measurement of the losses of this one in free-wheeling, the simulation of the performances of this one (indirectly after a power measurement), and finally the measurement of your lap times on track.
Moreover, it does not collect or share with anyone or anything the various GPS positions taken when it is active, and it instantly stops taking them when it is in the background.
And finally, it NEVER saves them in the permanent memory of the phone.
- These GPS positions however are not encrypted in the application, but this is not a privacy issue since as said above these data are used only for calculation purposes AND only when the application is active, and they are NEVER stored in the permanent memory of the phone.
- These GPS positions therefore transit ONLY in the RAM of the phone and ONLY while the application is active, they are NEVER in the permanent memory of the phone, and they are instantly deleted from this RAM as soon as the application is in the background or of course closed.

Note: Measurements performed:
- With 2 people on board (Edouard & David) and with full tank
- With 190/580 competition slick tires (equivalent in road dimensions: 190/52R15)
- In 5th gear from 2000 to 8100 rpm (rev limiter), since at this power level (415 hp), it was impossible for us to measure it either in 2 or in 3 or even in 4 due to insufficient grip!
- In both directions of the road then averaging of these two measurements according to the strict recommendation of PerfectPower in order to eliminate the effects of road slope and wind, and this even if in our case we have a perfectly flat measurement track and that no wind was blowing that day
- With the assistance of a 10 Hz external GPS (SkyPro XGPS160) communicating in bluetooth with PerfectPower and the use of the WIXGEAR universal magnetic windshield mount according to the strict recommandation of PerfectPower for the most accurate measurements possible
