Frequently Asked Questions
How do I reset my password?
On the sign-in screen, tap "Forgot Password?" and enter the email address associated with your account. You'll receive a password reset link within a few minutes.
How do I watch videos?
Open Fluo and swipe through the video feed. While a video plays, tap any word in the subtitles to see its meaning (and pinyin, for Chinese) and add it to your vocabulary for spaced-repetition review. Swipe up for the next video.
Where do the videos come from?
The videos are made by independent creators and published on TikTok. Fluo plays them inside TikTok's own embedded player, with the creator's name shown and a link to the original post (tap the creator's name to open their TikTok profile, or the TikTok logo on the video to open the post). Fluo keeps only a thumbnail and a preview copy of each video for the home screen; watching happens in TikTok's player, and Fluo does not redistribute the videos. The interactive subtitles are generated automatically by speech recognition and machine translation, so they can contain mistakes — use the Report option on any video to flag one.
Can I download videos for offline use?
Currently, videos require an internet connection to stream. We are exploring offline support for a future update.
How do I manage or cancel my subscription?
In the app, go to Profile > Subscription > Manage Subscription. This opens your App Store or Google Play subscription settings, where you can change or cancel your plan. You can also go to Settings > [Your Name] > Subscriptions on an iPhone, or Google Play > Payments & subscriptions > Subscriptions on Android. If you subscribed on our web app, email support@fluolearning.com for help cancelling it. Cancellation takes effect at the end of the current billing period. Deleting your Fluo account does not cancel your subscription, so cancel it first.
How do I restore my purchases on a new device?
In the app, go to Profile > Subscription > Restore Purchases. Make sure you're signed in to Fluo with the same account, and to the same Apple ID or Google account you used for the original purchase.
How do I delete my account?
Go to Profile > Account & data > Delete Account. This will permanently remove your account and all associated data. This action cannot be undone, and it does not cancel a Fluo Pro subscription — cancel that first. If you have already uninstalled the app, you can also delete your account from our account deletion page.
How do I report a video or a copyright concern?
Every video has an in-app "Report" option, including a reason for copyright concerns — tap it to flag content for our team. You can also email support@fluolearning.com. For copyright takedown requests and our DMCA process, see our Copyright & DMCA Policy.
How do I report or block another user?
You can block or report another user in the app; for a friend, open their profile from your Friends list. Blocking ends any friendship between you, and you no longer see each other anywhere in Fluo; they are not told. You can review blocked users in Profile > Friends & privacy. You can also email support@fluolearning.com. We review reports and act on violating content within 24 hours.
How do Fluo Friends work, and what do friends see?
You add friends only by sharing your friend code or invite link, or by entering theirs; there is no search or messaging. Friends see your name, outfit, and level and, if progress sharing is on, your streak, word counts, milestones, and activity, but never which words you know. Progress sharing is on by default; turn it off, stop friend requests, or reset your code in Profile > Friends & privacy. See our Privacy Policy for details.
What are AI credits and invite rewards?
Watching and rating videos is always free. AI actions, such as a video's translations, a text translation, or a question to the AI tutor, use AI credits: free accounts get 20 per day plus a one-time bonus of 150, and Fluo Pro removes the daily limit. When a friend joins with your invite code, they get a free week of Fluo Pro once they finish their first videos, and you get a free week when they come back on a later day. Limits apply; see our Terms of Service.
What are AI features and how do I enable them?
AI features generate personalized practice sentences, on-demand translations, and the AI tutor's answers. They run on third-party AI services (Google Gemini and the other providers listed in our Privacy Policy). You can enable or disable AI features at any time in Profile > AI-Powered Features. When enabled, the text you submit and the vocabulary needed to personalize the result are sent to the AI provider; your name, email, and account details are never shared. Video subtitles are generated separately by speech-recognition services and do not depend on this setting.
Can I use Fluo without AI features?
Yes. Without AI features enabled, you can still practice with Fluo's existing sentence library using spaced repetition. AI features are optional.
