Frequently asked questions
The most common questions answered.
How do I change the language of the app?
Open Saru, tap the gear icon in the top right to access Settings, and under "Language selection" choose English or Spanish. The change applies instantly.
Is Saru Pro a one-time purchase forever?
Yes. Saru Pro is a single $4.99 USD payment. Once purchased, you unlock all JLPT levels (N4 to N1) forever. No auto-renewals. No subscription.
How do I restore my purchase on a new iPhone?
On the Saru Pro screen, tap "Restore purchase". Make sure you are using the same Apple ID you originally bought with. Apple handles the restoration automatically.
Does Saru work without an internet connection?
Yes. All vocabulary, audio and lessons work offline. You only need a connection the first time to download the app and to process the Saru Pro purchase.
How is my progress calculated in each lesson?
Each lesson has 10 words. A word is marked as learned when you answer correctly the required number of times in a row. Your progress shows as "X/10" on the lessons screen.
Can I request a refund for Saru Pro?
Refunds are handled by Apple, not Saru. To request one, go to reportaproblem.apple.com with your Apple ID and select the Saru Pro purchase. Apple usually approves refunds for recent purchases.
Why can't I see all JLPT levels?
JLPT N5 is available for free. To access N4, N3, N2 and N1 you need Saru Pro. One-time $4.99 purchase, no subscriptions.
I found an error in a translation, what should I do?
Email us at hello@sarujp.com with the original Japanese word, the current translation and your suggested correction. We review every report and publish corrections in future updates.
Does Saru collect my personal data?
No. Saru does not require registration, does not collect your name, email or location. Your progress lives on your iPhone. For more detail, see our Privacy Policy.
How do I switch between dictionary, masu, ta and te form?
Go to Settings (gear icon in the top right) and under "Question form" choose the form you want to practice. The change applies to all verbs.
Is the app available for iPad?
Saru was designed for iPhone. You can install it on iPad and it works, but the interface is not optimized for the large screen. We are working on a native iPad version.
How do I contact the Saru team?
Email us at hello@sarujp.com. We respond within 1-3 business days. For urgent purchase or refund questions, contact Apple Support directly.
