Voi

Is the Voi app safe?

Voi is one of the better-behaved scooter operators, but its app is not light on data. We found no fine from any privacy or consumer regulator, and Voi has published accident rates and a goal of zero deaths and severe injuries, which not every rival does. The catch is advertising: Apple's label says Voi may use your contact details and identifiers to track you across other companies' apps, and Google Play says it shares your email and phone number for marketing. In 2019 a flaw also left about 460,000 users' contact details visible online. We score it 56/100, just below Dott (57).

Voi Technology AB is based in Stockholm. Its 2025 annual report says it runs more than 160,000 vehicles in over 130 towns and cities across 13 countries, has served more than 450 million rides, and has more than 4 million active riders a year. The app is rated 4+ on the App Store.

What Voi collects and shares

Apple's label has three parts. Used to track you: contact info and identifiers. Linked to you: purchases, location, contact info, user content, identifiers and usage data. Not linked to you: health and fitness data, financial info, identifiers and diagnostics. Tracking with contact info usually means an email address or phone number is matched with ad platforms to target or measure ads.

Google Play is consistent with that. It says Voi shares your email address and phone number with other companies for advertising or marketing, user IDs for fraud prevention, and approximate and precise location for app functionality and analytics. It also lists app interactions, crash logs, device IDs and payment info among shared data. Data is encrypted in transit, and you can ask Voi to delete it.

Voi's privacy notice, published as a PDF linked from its website, fills in more. Where Voi checks age or identity, it may ask for a driving licence or other ID and a selfie, and with your consent it uses automated face matching and age estimation on them. Some vehicles carry cameras, and the notice covers ride images without audio and the passers-by they capture. Voi also records injury details when you or a bystander report an incident. It may send you marketing for third parties' products with your consent, and it passes location, ride, payment and device data to marketing partners to run and measure campaigns. Data is kept "as long as is necessary", and account data is deleted when the account ends, except what Voi must keep by law. That vague retention rule is why transparency and control scores 55 rather than higher.

The 2019 data leak

In 2019 data journalists at Germany's Bayerischer Rundfunk found that they could view the names, email addresses and phone numbers of about 460,000 Voi users with a few clicks. Voi confirmed the incident. It said a user had found a way into the part of its system that stored ride receipts, that the flaw was fixed within an hour, that no card or PayPal details or passwords were exposed, and that it had reported the breach to Sweden's data protection authority under GDPRGDPRThe EU's General Data Protection Regulation, which sets rules on how organisations collect and use personal data and allows large fines.More in the glossary.

That was seven years ago and we found nothing since. It still counts under our ten-year window, and Voi publishes no bug bounty that we could find, so security scores 55.

Rider safety

Voi has been more open about accidents than most rivals. Its second safety report, released in April 2023, counted 5.45 major and severe accidents per million kilometres across more than 120 million rides from January 2021 to December 2022, in 11 countries. Voi itself warned that the figure depends on riders reporting accidents and leaves out minor injuries. Its 2025 annual report repeats a Vision Zero goal of no deaths or severe injuries and says the rate of severe accidents per million rides fell again in 2025, though the report text we read gives no new figure.

The app offers a reduced-speed mode for first-time riders, and the listing tells riders to stay off pavements, never ride under the influence, wear a helmet and ride one person per vehicle.

Voi and regulators

We found no privacy or consumer protection fine on Voi in any of its markets. When Italy's AGCM fined e-scooter operators in Rome in 2026, the cases covered Lime, Dott and Bird; Voi was not among them. Because no large regulator has examined Voi in depth that we know of, and it publishes no independent security audit, regulatory record scores 86 rather than 90 or more.

How to ride Voi more safely

1. Refuse tracking when iOS asks; this stops Voi using your identifiers for cross-app ads on iPhone.
2. Allow location only while using the app.
3. Switch on reduced-speed mode for your first rides.
4. Check the brakes and lights before you set off, and end the ride if anything feels wrong.
5. Ask Voi to delete your account and data when you stop riding.

How we scored it

Regulatory record (86) is the strongest factor: no fine anywhere we looked. Privacy (46) is the weakest, because contact details and identifiers are used to track you and email and phone number are shared for marketing. Scams and harmful content (62) credits Voi's published accident data. For Lime's lighter tracking label, see Lime.
