Très satisfait de mon expérience ! On voit que le vendeur prend son travail à cœur et qu’il cherche vraiment à proposer un dictionnaire de qualité pour liseuse. Même quand ce n’est pas simple, il ne lâche pas et fait en sorte que le résultat soit à la hauteur. Rare de trouver quelqu’un d’aussi sérieux et impliqué. Je recommande sans hésiter !

Is native PocketBook/Vivlio dictionary support available?
Native dictionary support on PocketBook and Vivlio devices is not available yet due to technical limitations. However, you can use our dictionaries on these devices by installing KOReader, which provides full support. We are actively working on a solution for native support and will update our users when it becomes available. For guidance or updates, contact us!

How often are dictionaries updated?
All dictionaries are updated twice a month—and even faster if you need it! If you find a dictionary isn’t working perfectly for your device or language pair, let us know. We’ll investigate, fix, and update the files quickly—often within days—so you always have the best possible experience. Your feedback helps us improve for everyone! All purchases include lifetime updates.
Why is the price the same for all dictionaries, regardless of size?
We offer a simple, one-time price for each dictionary, no matter its current size. When you purchase, you receive lifetime access to all future updates and improvements for that dictionary. This means your dictionary may start small or large, but as we add new words, definitions, and features, you'll always have the latest version at no extra cost.
