Data safety

Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region, and age. The developer provided this information and may update it over time.
app is painfully slow, it takes too long to scan the codes, like over 15mins to scan and "analyze", very poorly written app because others scan much quicker and also there should be a quick scan feature that only scans the module you need, but this app lacks that feature and it takes forever to do anything it has become useless. I change to other, or use my handheld scanner and it is much quicker it's not even close, like 1-2mins is really how long this should take.

app is garbage, downloaded for my mb check engine light and took 15 minutes to tell me what it was. once I figured it out I tried to clear it. another 15 minute wait and still not clear. it says billed monthly in the app. dont fall for that its billed annually. im out 80 bucks for something that doesn't work. response: your app says billed monthly when purchasing license. this is not the case and it is billed annually. do not lie to cover your app on here.

The scanner worked reasonably well for a time. By the second year I purchased service, my scanner would not read my vehicles properly at all and I was expected to buy another scanner. I chose not to and let the second year run out. Carly stored my credit card info, where in Google play I have no subscriptions at all, and took it upon themselves to charge my card for a third year, stealing from me. Now they hide from returning my money behind Google policy that does not apply to me.
