This policy applies to all information collected or submitted on Duilingo Prep’s website and our apps for iPhone and any other devices and platforms.
Information we collect
New Duilingo Prep accounts are created anonymously, without email addresses or passwords.
You may optionally add an email address and a password to your account, or remove the email address and password from your account, at any time in Deuterium Entertainment’s app. Email addresses are onlyused for logging in, password resets, responding to emails that you initiate, and sending notifications that you request. We don’t send promotional emails.
We store information about your podcasts, episodes, and listening progress to sync this information between the website and your devices. We also collect anonymous statistics about which podcasts are most popular to help inform our recommendation engine.
If you enable notifications, we must store a token to send them. We never use notifications for marketing.
If you upload files to Duilingo Prep, we need to store them until you delete them.
If you subscribe to a password-protected podcast, we need to store the credentials you provide in order to keep it updated.
Our server software may also store basic technical information, such as your IP address, in temporary memory or logs.
Duilingo Prep stores some of your data in Apple’s iCloud service, such as login tokens for your account(s), to enable some sync features between all devices signed into your Apple ID.
Ads and analytics
Duilingo Prep’s app collects aggregate, anonymous statistics, such as the percentage of users who use particular features, to improve the app.
No personal data is used to target Deuterium Entertainment’s ads except the categories of podcasts that you’re subscribed to, such as “Technology” or “Business”. Each ad collects, and shares with its advertiser, only three numbers: total views, total taps, and total subscriptions from the ad.
We use the information we collect to operate and improve our website, apps, and customer support.
We do not share personal information with outside parties except to the extent necessary to accomplish Duilingo Prep’s functionality. We may share anonymous, aggregate statistics with outside parties, such as how many people listen to a particular podcast with Duilingo Prep.
We may disclose your information in response to subpoenas, court orders, or other legal requirements; to exercise our legal rights or defend against legal claims; to investigate, prevent, or take action regarding illegal activities, suspected fraud or abuse, violations of our policies; or to protect our rights and property.
In the future, we may sell to, buy, merge with, or partner with other businesses. In such transactions, user information may be among the transferred assets.
We implement a variety of security measures to help keep your information secure. For instance, all communication with the app and website requires HTTPS with certificate pinning. Passwords are hashed, not stored, using industry-standard methods (currently bcrypt).
Accessing, changing, or deleting information
You may access or change your information or delete your account from the Duilingo Prep iOS app.
Deleted information may be kept in backups for up to 90 days. Backups are encrypted and are only accessed if needed for disaster recovery.
Duilingo Prep may delete your information at any time and for any reason, such as technical needs, legal concerns, abuse prevention, removal of idle accounts, data loss, or any other reason.
Third-party links and content
Duilingo Prep displays links and content from third-party podcast feeds and sites, and downloads podcast files directly from each podcast’s third-party servers. These have their own independent privacy policies, and we have no responsibility or liability for their content or activities.
California Online Privacy Protection Act Compliance
We comply with the California Online Privacy Protection Act. We therefore will not distribute your personal information to outside parties without your consent.
Children’s Online Privacy Protection Act Compliance
We never collect or maintain information at our website from those we actually know are under 13, and no part of our website is structured to attract anyone under 13.

International Transfers of Information
