If something isn’t working in the Grifko app or you have a question, write to us at vass@vassweb.com. It helps if you tell us your iPhone model, your iOS version and what exactly happened.
Frequently asked questions
What does the Grifko app contain?
18 short business lessons in 3 modules. Each lesson has a text, a practical exercise and a quiz of 5 questions; you have mastered a lesson when you get 4 out of 5 right. You can search lessons and topics. The lessons are for reading — the app has no audio versions. The app and its lessons are in Slovak.
How do I set up examples for my business?
In the menu (the ⋯ icon at the top right), choose Moja firma (My business) and pick your trade and the size of your business. The examples in the lessons then adapt to your trade and the exercises to the size of your business. You can change this at any time.
Do I need the internet?
Not for reading the lessons — they are part of the app. You only need the internet to buy the full version and to restore purchases.
Do I need an account or to sign in?
No. The app has no account and no sign-in, and it sends nothing to our servers.
Which devices does the app work on?
iPhone with iOS 17 or later.
Purchases and subscriptions
What is free and what is paid?
The first module (Automation from scratch) is free. The other two modules are unlocked by a monthly subscription or a one-time Lifetime purchase. Payment is handled by Apple through the App Store; you will see the current price directly in the app.
I bought the full version, but the app is still locked. What can I do?
In the menu (the ⋯ icon at the top right) or on the unlock screen, tap Obnoviť nákupy (Restore purchases). You need to be signed in with the same Apple ID you used for the purchase and be connected to the internet.
How do I cancel my subscription?
Subscriptions are managed by Apple, not by the app. To cancel:
- Open Settings and tap your name.
- Tap Subscriptions.
- Select Grifko and tap Cancel Subscription.
You need to cancel at least 24 hours before the end of the current period, otherwise the subscription renews. You keep the full version until the end of the period you have paid for. Apple describes the steps in detail on its page Cancel a subscription from Apple. The Lifetime purchase is a one-time payment and nothing renews.
How do I ask for a refund?
Payments are handled by Apple, so refunds are requested from Apple at reportaproblem.apple.com. We have no access to your payment details.
Your data
What does the app store about me?
Only your progress in the lessons, your quiz results and your Moja firma (My business) setting (trade, business size). All of it stays on your phone only. Details are in the privacy policy.
How do I delete my data?
Uninstall the app — this removes your progress, quiz results and settings from your phone. The app has no separate button to delete your progress. Our servers hold nothing about you from the app, so there is nothing to delete there. If you have emailed us and want the email deleted, write to us at vass@vassweb.com.
