FAQ

Is Cakeday free?

Yes. Cakeday is completely free with no in-app purchases, subscriptions, or hidden paid tiers. All current and future updates will remain free.

Does Cakeday collect my data?

No. Cakeday does not collect or transmit your app data to developer-operated servers. There are no advertising SDKs, analytics frameworks, or behavioral trackers in the app. Data stays on your iOS device or, if you enable iCloud Sync, in your private iCloud® container. See the Privacy Policy for details.

How do I add a lunar birthday?

When adding or editing a birthday, tap the calendar toggle at the top of the date picker and select “Lunar.” The interface switches to lunar mode with support for leap month calculations. See the Lunar Calendar guide for details.

What is Birthday Alarm?

Birthday Alarm is the high-priority reminder for the day of the birthday. On supported iOS versions, enabling it requests Alarm access and delivers the same-day reminder in an alarm-style format. Advance reminders still use standard notifications, and the app falls back to regular notifications automatically if Alarm access is unavailable.

Can I import existing backups or shared files?

Yes. Cakeday can import .cakeday, JSON, CSV, and .cakeshare files. Full backups and general imports support overwrite and incremental import, while .cakeshare import supports per-person selection and duplicate warnings. See the Backup & Import guide for details.

What happens if iCloud Sync is enabled during overwrite import?

If iCloud Sync is already enabled, overwrite import restores the local data first and then pauses iCloud Sync. This gives you time to review the imported state before you decide when to resume sync and merge behavior.

What happens if I delete the app?

If iCloud sync is enabled, your data is preserved in your Apple ID’s CloudKit container. Reinstalling Cakeday will restore all data automatically. If iCloud sync is disabled, all local data is permanently deleted when the app is uninstalled.

How does CakeShare work?

Cakeday uses CakeShare for sharing. Single records can be shared via URL deep links. For bulk data, including avatars and groups, Cakeday generates protected .cakeshare files and can add an optional password when needed. See the CakeShare guide for details.

What languages are supported?

Cakeday supports English, Simplified Chinese (zh-Hans), Traditional Chinese (zh-Hant), and Japanese. The app follows your device language and also works with iOS per-app language settings.

Can I change the date display format?

Yes. In Settings > Display Settings, you can choose System, Year / Month / Day, Month / Day / Year, or Day / Month / Year. The same preference is used by widgets and Apple Watch.

How does Calendar sync work?

When enabled for a person, Cakeday uses EventKit to create a recurring annual all-day event in the system Calendar. The app also provides Auto Sync, Sync Now, failed-sync retry, and Remove All Events controls. Later edits are reflected automatically, and future sync runs can recover the Cakeday calendar or missing events if they were removed externally.

How is the Ascendant (Rising Sign) calculated?

The Ascendant requires a precise birth time and geographic coordinates. Enter the birth time and select a city from the built-in database, and Cakeday uses AstroCore to compute the corresponding rising sign.

How does Spotlight Search work with Cakeday?

Cakeday indexes your birthday records using CoreSpotlight. You can swipe down on your Home Screen and search by name, pinyin romanization, or zodiac sign. Matching results appear directly in the system search results with countdown information, without opening Cakeday.

Pinyin search is supported because Chinese users typically type pinyin on their keyboard — without pinyin indexing, searching “zhangsan” would not find “张三”. Cakeday indexes both the original name and its pinyin so that either input method works.

Known limitation: Due to an iOS system limitation, Spotlight search with CJK (Chinese/Japanese/Korean) characters is unreliable — searching Chinese names, zodiac signs, or other CJK text may not return results. This is a CoreSpotlight indexing issue, not specific to Cakeday. As a workaround, search using pinyin romanization (e.g., type “zhangsan” instead of “张三”) or English terms for reliable results.

Can I use Siri to check birthdays?

Yes. Cakeday integrates with App Intents and Shortcuts. You can ask Siri about today’s birthdays, upcoming birthdays, and specific people, and you can build shortcuts for search, add, and random-entry actions. This works on iPhone, iPad, Apple Watch, and Mac.

Known limitation: Siri may not recognize Chinese names accurately when spoken. For best results, use Siri in English (e.g., “upcoming birthdays”) or use Shortcuts for queries involving Chinese names.

Is there a faster way to access common actions?

Yes. Control Center can host Add Birthday, Upcoming Birthday, and Birthday Countdown controls, and long-press app icon quick actions can jump straight into Search, Upcoming, Add Birthday, and Random Friend.

What does the badge number on the app icon mean?

The badge shows how many people have a birthday today. It updates automatically as scheduled notifications and date changes are processed. If no one has a birthday today, the badge stays clear.
