Frequently Asked Questions
What's included in the free plan?
The free plan includes basic grammar and spelling checks, 5 AI-powered grammar explanations per day, documents up to 10,000 words, 10 snippet slots, and the ability to ignore suggestions with one click. It's perfect for trying out the tool and occasional writing needs.
Can I cancel my subscription anytime?
Absolutely. You can cancel with one click from your account settings. No phone calls, no retention emails, no questions asked. If you cancel, you'll keep access until the end of your billing period, and you won't be charged again.
Is there a trial period for Pro?
We don't offer traditional trials because our free plan is genuinely useful. Try the free version first—it's not limited to 7 days or designed to frustrate you into upgrading. When you're ready for unlimited explanations and advanced features, upgrade to Pro.
How does billing work?
Monthly plans are billed every month. Yearly plans are billed once per year (saving you 40%). Lifetime is a single payment with no renewals ever. You'll receive an email receipt for every charge. No auto-renewals without clear notice.
Is my data safe?
Yes. We're based in Switzerland and take privacy seriously. Your documents are encrypted in transit and at rest. We don't train AI models on your writing. We don't sell your data to third parties. We don't track you across the web. Your writing is yours, period.
What happens if I downgrade from Pro to Free?
You'll keep access to Pro features until the end of your billing period. After that, you'll return to the free plan limits. Your saved snippets beyond the first 10 will remain stored but read-only—you can still view and use them, but you won't be able to add new ones until you upgrade again or delete some.
Do you offer refunds?
Yes. If you're not satisfied within 30 days of purchase, we'll refund you in full, no questions asked. Just email us at hello@grammar-mentor.ch.
