以下说明适用于 1.1 更新。各地区可下载版本以 App Store 为准。These terms describe version 1.1; check the App Store for availability.
Forma 是本地视频格式转换工具，支持系统媒体框架能够读取的常见视频。损坏、加密、受 DRM 保护或系统不支持的文件不保证能够转换。请先确认导出可播放，再删除原视频。
本次升级的三天试用仅开放通用 MP4 的导入、预览、转换、保存流程。HEVC、提取音频和视频瘦身需要一次性买断。三天结束后，所有转换需买断；导入预览、设置和已有导出文件的访问不以重新付费为条件。
首次使用本版的新用户通过 Apple 领取零元非消耗型项目“3 天试用”（com.tongstudio.forma.trial.3day），从已验证的首次领取交易时间起计算连续 72 小时，不自动扣费。领取前会说明功能限制及到期后的买断价格。旧用户保留已有试用起点；既有 Keychain、旧版本地记录和 Apple 核验的旧版原始下载日期取最早有效时间，不重新发放三天。重新下载、恢复购买、离线或核验失败均不重新计时。领取和恢复可能需要连接 Apple；同一 Apple 账户恢复原领取时间。不同 Apple 账户或完全丢失系统记录等边界不承诺绝对防绕过。
Forma Lifetime（com.tongstudio.forma.lifetime）是非消耗型一次性买断，不是订阅，不自动续费。美国区配置价由 USD 5.99 调整为 USD 3.99。实际金额、税费、币种和商品可用性以 Apple 购买确认页为准；其他地区不直接套用美元划线价。
已购用户可通过同一 Apple 账户恢复购买。Apple 处理购买、账单、退款及撤销。退款或撤销可能使买断权益失效。支持：tongjia323@gmail.com。
Forma converts local media supported by the device’s system frameworks. Compatibility with damaged, encrypted, DRM-protected or unsupported files is not guaranteed. Check the exported file before deleting the original.
This upgrade offers a three-day Universal MP4 trial, including import, preview, conversion and saving. HEVC, audio extraction and Slim Video require the lifetime purchase. All conversion requires purchase after trial expiry. Import previews, settings and access to already-exported files remain accessible.
New users claim the zero-price non-consumable “3-day Trial” (com.tongstudio.forma.trial.3day) through Apple. The trial lasts 72 consecutive hours from the verified original claim transaction, with no automatic charge. Its restrictions and the lifetime price are disclosed before claiming. Existing users retain their earliest valid trial start from Keychain, legacy settings or the verified original acquisition date of an earlier build. Reinstalling, restoring, being offline or failed verification do not restart the period. Claiming and restoring may require Apple connectivity; the same Apple Account restores the original claim date. Prevention is not guaranteed across different Apple Accounts or every complete record-loss scenario.
Forma Lifetime (com.tongstudio.forma.lifetime) is a non-consumable, one-time purchase with no subscription or automatic renewal. The US configured price changed from USD 5.99 to USD 3.99. Apple’s confirmation sheet determines the actual amount, taxes, currency and product availability. Other storefronts do not inherit the US reference price.
Restore the purchase using the same Apple Account. Apple handles billing, refunds and revocations; revocations can remove purchased access. Support: tongjia323@gmail.com.
