Vellio stores data on your device and, when iCloud is available, in your personal Apple iCloud database. The developer does not operate a server that can browse your private Vellio content.

Confirm that both devices use the same Apple Account, iCloud Drive is enabled, Vellio is allowed to use iCloud, and both devices have a network connection. Apple controls iCloud sync timing, so changes may take a little while to appear.

Vellio revokes CloudKit access. Removal on the recipient’s device depends on iCloud syncing and may not be immediate. Anything previously copied, photographed, screenshotted or exported by a recipient cannot be remotely deleted.

Open Vellio’s subscription screen and choose Restore Purchases while signed in with the Apple Account used for the purchase. Purchases and refunds are managed by Apple.

Without a subscription, Vellio allows up to 10 gift cards, 10 shopping receipts and 10 membership cards, with a combined limit of 20 across those three categories. Received shared items count toward these limits. Bills are not included in this quota.

Use Backup in Vellio settings to export a file, then save it somewhere secure. Backups can contain card numbers, PINs, photos and other sensitive content.

Delete individual records inside Vellio. Because iCloud may retain synced app data after the app is removed, also review your iCloud storage settings if you want to remove all cloud-held app data.

Vellio 将数据保存在你的设备上；在 iCloud 可用时，也会保存在你的个人 Apple iCloud 数据库中。开发者不运营能够浏览你私人 Vellio 内容的服务器。

请确认两台设备使用同一个 Apple 账户、已开启 iCloud 云盘、允许 Vellio 使用 iCloud，并且设备均已联网。iCloud 同步时间由 Apple 控制，变更可能需要一段时间才会显示。

Vellio 会撤销 CloudKit 访问权限。内容从接收方设备移除取决于 iCloud 同步，可能不会立即完成。接收方此前复制、拍照、截图或导出的内容无法远程删除。

使用购买时的 Apple 账户登录，在 Vellio 订阅页面选择“恢复购买”。购买和退款由 Apple 管理。

未订阅时，Vellio 最多允许添加 10 张礼品卡、10 张购物收据和 10 张会员卡，且这三类合计不超过 20 条。接收的共享项目也计入额度；账单不计入这一额度。

在 Vellio 设置中使用备份功能导出文件，并将其保存在安全位置。备份可能包含卡号、PIN 码、照片和其他敏感内容。

你可以在 Vellio 内删除单条记录。卸载 App 后，iCloud 仍可能保留已同步的数据；如需删除全部云端 App 数据，也请检查 iCloud 储存设置。
