Opalyn

Free offline mode

Offline mode is free for one local device/workspace and does not require a cloud account.

Online trial

The 14-day online trial starts server-side when an owner creates or upgrades to an online tenant. Device clock changes cannot extend the trial.

After expiry

After trial expiry, online access may become read-only/export-only unless a verified active online subscription entitlement exists. Offline free mode remains available.

Store billing

Online cloud sync is a tenant/workspace subscription with a target price of USD 1/month or USD 10/year, subject to store price tiers, local currency, taxes, and storefront rules. Android uses Google Play Billing and iOS uses Apple In-App Purchase/StoreKit where required. Backend verification is required before entitlement becomes active.
