Need help with Transsera?

Tap Web Login and sign in on Coursera's own page, just like on the website. Your password stays on Coursera's page. Transsera never sees it. After you sign in, the app keeps you signed in between launches.

Tap Trouble signing in? on the sign-in screen. There you can:

• Try again reloads the sign-in page without signing you out of anything.
• Compatibility lets you choose how the built-in browser presents itself to the website: Standard (recommended), WebKit or Desktop. Tap Apply to reopen the sign-in page in that mode.
• Browser session lets you sign in with a session from a browser on your computer (see the next question).

Google sometimes refuses sign-in inside apps' built-in browsers. If that happens, try another compatibility mode, sign in with your Coursera email and password, or use a browser session.

1. On your computer, sign in to coursera.org in your browser.
2. Open the browser's developer tools → Cookies → coursera.org.
3. Copy the value of the CAUTH cookie.
4. In the app, open Trouble signing in? → Browser session, paste the value and tap Log in.

The value is a key to your account. Use only your own session and never share it with anyone, including me. Coursera may end the session earlier than expected, in which case just repeat the steps.

Open Options → Logout. This removes the Coursera session and coursera.org website data from the app. Then sign in with the other account. When a different account signs in, the previous account's downloaded lectures and cached courses are deleted from the device.

While a lecture plays with subtitles, tap a word, or select a phrase, in the subtitles. The translation appears above it. Tap the translation to open a detailed page from the translator. Word translation is part of the Subtitles Translation purchase.

Choose the translator in Options → Subtitle Translation. Pick the language to translate into from the subtitle settings in the player. The list comes from the selected service, so it can differ between Google and Yandex.

Translation needs an internet connection, even for downloaded lectures. Check your connection and try again. If the problem continues with one translator, switch to the other one in Options and let me know.

Yes, on iPad with an external keyboard:

On launch, Transsera returns to the last week you opened and highlights the last video, without starting playback. Tapping it continues from the saved second. A lecture is marked as watched after you play more than 90% of it or get within the last 20 seconds.

Tap the download button next to a lecture, or next to a week to download all of it. Downloads need the Offline Mode purchase. Downloaded lectures play without an internet connection, with their subtitles.

Delete a single download, or all downloads of a week, with the delete button in the lecture list. Deleting the app removes all downloads.

Open Options → Purchases and tap Restore purchase. Make sure you're signed in to the App Store with the same Apple ID you used to buy. If it still doesn't work, email me with the date of the purchase. You'll find it in your App Store purchase history.

No. Subtitles Translation and Offline Mode are one-time purchases. Nothing renews or charges you again.
