Calvance Terms of Use

Last updated: November 7, 2026

These terms apply to Calvance across platforms and to its account and cloud services. For versions obtained through the App Store, the App licence remains governed by the Apple Standard End User License Agreement. These terms describe Calvance’s service and purchase rules and do not replace or limit that licence; if they conflict on an App licensing matter, the Apple agreement applies. Our Privacy Policy explains how we process information.

Using Calvance

Calvance helps you organize calculations on a canvas. You may use the App for lawful personal or business purposes in accordance with these terms and the applicable store terms. You must not misuse accounts, interfere with the service, bypass purchase verification, or upload material you have no right to use.

Check important calculations, inputs, units, rounding and reference exchange rates independently. Calvance is a calculation tool; its output is not professional financial, medical, engineering or legal advice. Exchange rates may be dated reference values rather than prices available for an actual transaction.

Accounts and your canvases

An account is optional for local use. Keep your sign-in method secure and contact us if you suspect unauthorized access. Cloud synchronization requires an eligible Premium subscription, sign-in and an internet connection. A local canvas is not automatically a cloud backup; follow the App’s account and synchronization choices.

You retain rights to your canvas content. You permit us to process it only as needed to provide the features you choose, operate and protect the service, and meet applicable obligations described in the Privacy Policy. Export copies of work you need to keep. Device backups, network availability and synchronization do not guarantee recovery of every edit.

Local purchases and Premium

Local Pro and Local Unlimited are one-time purchases for the local features shown in the App. Local Pro supports up to 20 canvases; Local Unlimited removes that limit. Neither includes cloud synchronization. Where offered, an upgrade from Local Pro requires a verified eligible purchase from the same store.

Premium provides the features displayed in the App for the paid subscription period. You may subscribe without a Calvance account; sign-in and account association are needed for cloud synchronization and cross-platform Premium access. Once associated, a subscription does not move to another account simply because you switch accounts. Local one-time purchases are restored through the purchasing store, not transferred across stores by signing in to Calvance.

Billing, renewal and cancellation

The App Store processes purchases on Apple platforms; Google Play processes purchases on Android. Review the local price, billing period, applicable taxes and any offer displayed by the purchasing store before confirming. A subscription renews automatically unless canceled through the store. Monthly or yearly plan changes, their effective date and charges follow the terms presented in the purchase flow.

Manage or cancel subscriptions through the store where you purchased: App Store or Google Play. Cancellation normally stops future renewals; access continues for the paid period unless a refund, revocation or another applicable store rule changes it. Refund requests are handled under the store’s rules and applicable law. These terms do not remove statutory refund or consumer rights.

Purchases made through different stores can create separate charges. Before subscribing again, restore your purchase or sign in to the account already associated with Premium and check existing subscriptions.

Ending use or deleting an account

You may stop using Calvance at any time and request account deletion, including without reinstalling the App. Deletion permanently removes the account and associated cloud data as explained on that page. Export needed canvases first.

Deleting the account or uninstalling the App does not cancel a subscription or automatically refund a purchase. You can delete an account while subscribed. Local permanent purchase rights and the minimum records needed to restore or reconcile purchases are handled as described in the Privacy Policy.

Service changes and your rights

We may provide updates or change features to maintain compatibility, security and service operation. Material changes affecting purchased features will be communicated where required. We do not promise uninterrupted availability or support for every device. Nothing in these terms excludes liability or rights that applicable law does not allow to be excluded.

If we update these terms, we will update the date and provide notice of material changes where required. New terms do not override applicable mandatory rights or the store’s terms for a completed purchase.
