Frequently asked
Are my numbers private?
Yes. Kârly stores your cost / sell-price inputs only on your device, in local app storage. We do not upload them, sync them to a server, or include them in any analytics event. If you uninstall the app, the data is gone.
Which marketplaces are supported?
Trendyol, Hepsiburada, n11, Çiçek Sepeti, Pazarama, Amazon US, Etsy, eBay, Shopify, plus a Custom marketplace where you set your own rates. We add new marketplaces based on user requests — write to us with the marketplace name and your country.
How accurate are the fee models?
We model each marketplace's published default commission, listing, and payment processing fees. Promotional and category-specific overrides are not modelled — if you're in a special program, treat the calculator output as a high-confidence estimate, not a settlement statement.
How do I cancel a subscription?
Subscriptions are managed by Google Play. Open the Play Store app → tap your profile picture → Payments & subscriptions → Subscriptions → Kârly → Cancel. Cancellation takes effect at the end of the current billing period.
Where can I report a bug or request a feature?
Email hi@nexutility.com with the app version (Settings → About), your device model, and a description of what happened. Screenshots help. We reply within one business day.
What about iOS?
Android-first launch. iOS is on the roadmap — it lands after Android revenue covers the Apple Developer Program fee. Write to us if you'd like to be notified.
