Lectly
Privacy Policy
In short. No account, no analytics, no advertising SDKs and no tracking. Lectly never asks you to sign in to Google or YouTube.
Your courses, notes, doubts, photos, flashcards, goals, streaks and progress are stored only on your phone.
To show lecture details, Lectly looks up public YouTube information. Our server sees only public video and playlist IDs and a random install number that isn't linked to you.
Lectures play in YouTube's embedded player, a Google service, and the Google Privacy Policy applies to it.
What stays on your phone
- Courses, sections, lecture order, progress and watch position, notes, doubts and answers, notebook photos, flashcards and their review history, goals, streak days, exam names and dates, reminders and settings.
- Your first name, if you type it. It is used for the greeting and the "from" line of a course you share.
- Widgets, the Live Activity, Siri and Shortcuts, and Spotlight read the same on-device data through the app's private storage.
- Backups are
.lectlyfiles that you choose where to save. We never receive them. - Settings › Delete all data removes everything at once. Uninstalling the app does too.
What reaches our server
Lectly's server at lectly.wdlab.app is contacted when you add a playlist, or when Lectly refreshes lecture details (at most every 25 days).
- What is sent: public YouTube playlist and video IDs, and a random install number (made on your phone and tied to nothing) used only to limit request rates.
- What the server does: it asks the YouTube Data API for the public titles, channels, lengths, thumbnails and chapters, and caches those public answers for up to 24 hours. The cache holds nothing about you.
- Logs: web access logs are switched off. Your IP address is used briefly to limit request rates and is stored only as a one-way hash, for up to an hour. If a request fails, the server's error log may record the IP address with the error; error logs are deleted after 14 days.
- We never sell, share or analyse any of this.
Requests your phone makes to YouTube and Google
- The player. Lectures play in the official YouTube embedded player in privacy-enhanced mode (youtube-nocookie.com). When you play a lecture, Google receives the request as it does for any embedded YouTube video, and YouTube may show ads. See the Google Privacy Policy.
- Single lectures. Adding one lecture looks up its title through YouTube's public oEmbed address (youtube.com/oembed), directly from your phone.
- Thumbnails load from YouTube's image servers.
YouTube API Services
Lectly uses YouTube API Services. By using Lectly you agree to be bound by the YouTube Terms of Service. How Google handles data is described in the Google Privacy Policy.
YouTube information stored on your phone (titles, channels, lengths, thumbnails and chapters) is refreshed every 25 days and deleted after 30 days if it can't be refreshed. Lectly never accesses your Google account, so it holds no authorisation for you to revoke. Google's security settings page is where you manage apps connected to your account.
Permissions
- Camera and photos: only when you add a photo of a notebook page to a note. Photos stay on your phone.
- Notifications: only if you turn on the daily study reminder.
- Lectly does not use location, contacts, the microphone or tracking.
On-device card suggestions
On supported iPhones, "Suggest cards" uses Apple's on-device model. Your notes are processed on the phone and are not sent to us or to Apple.
Children
Lectly is a general-audience study app. It does not collect personal information from anyone, including children.
