No. Tilbo works fully without signing in — your progress is saved on your device. Signing in with Apple or Google backs it up, so it’s restored if you reinstall or switch devices.

Open Me and sign in with the same Apple or Google account you used before. Your child profile, progress and journal come back automatically. Journal photos are stored only on the original device.

Tilbo only unlocks builds you can make with the tiles you have. Update your tile counts in Me → Child profile. A locked build lists exactly which shapes are missing.

Builds use standard shapes found in the common sets: small and large squares, rectangles, and equilateral, right and tall triangles. Sizes vary slightly between brands, so mixing brands in one build can be tricky.

Yes. The build library is included in the app and kept up to date when you’re online. Signing in and account deletion need a connection.

Use the EN / 中文 switch at the top of Me.

Open Me → Delete account. This permanently deletes your account and cloud backup and clears Tilbo data from the device. Apple accounts are asked to confirm with Apple once more. Can’t get into the app? Email us from the address on your account and we’ll delete it for you.

Tilbo is a tool for parents — children build offline with you, not on the screen. Magnetic tiles contain magnets: always supervise play and follow the manufacturer’s safety guidance. See our Terms.

不需要。不登录也能使用全部功能，进度保存在设备上。用 Apple 或 Google 登录后会云端备份，重装或换机也能找回。

打开「我的」，用之前的 Apple 或 Google 账号登录，孩子档案、进度和成长册会自动恢复。成长册照片只保存在原设备上。

Tilbo 只解锁你手头的磁力片能拼出来的作品。可以在「我的」→「孩子档案」里更新各形状的数量；锁定的作品会列出具体缺哪些形状。

作品只使用常见套装里的标准形状：小正方形、大正方形、长方形，以及等边、直角和高三角形。不同品牌尺寸略有差异，同一个作品混用不同品牌可能不太好拼。

可以。作品库内置在 App 中，联网时会自动更新。登录和删除账号需要联网。

在「我的」顶部使用 EN / 中文 切换。

打开「我的」→「删除账号」。这会永久删除你的账号和云端备份，并清除设备上的 Tilbo 数据。Apple 账号需要再用 Apple 确认一次。无法进入 App？请用账号绑定的邮箱给我们发邮件，我们会帮你删除。

Tilbo 是给家长用的工具——孩子是和你一起在线下拼搭，而不是盯着屏幕。磁力片内含磁铁，请始终看护孩子玩耍，并遵守厂商的安全提示。详见使用条款。
