Experts at internet research non-profit Mozilla studied more than 20 pregnancy and period tracking apps for privacy and security features and said the results were grim. “Most of these products collect vast amounts of personal data, and then share it widely,” said Ashley Boyd, the vice-president of advocacy at Mozilla.
Of the 10 pregnancy apps, 10 period trackers and five wearables reviewed in the study, only seven were deemed to have safe user data and privacy practices. Most collected large amounts of personal data and shared it with third parties such as data brokers and advertisers. The study also examined security practices and found eight apps failed to meet minimum security standards and allowed weak passwords. Many apps also offered unclear policies surrounding police warrants for user data or made no stance on such requests.
