Privacy Policy

Last updated: November 7, 2026

This policy covers the Frettio iPhone and Apple Watch apps and this website. Frettio is maintained by an independent developer and provides practice records, tuning, a metronome and guitar references. Privacy contact: support@cocoboloa.com.

Data on your devices

Practice records (dates, duration, project content and edits), active timers and recovery information, practice projects, recent durations, tuning presets and preferences are stored on your device. We do not operate an app account system or a business server receiving your practice records or audio. The apps have no advertising, cross-app tracking or third-party analytics SDKs.

Microphone and audio

With microphone permission, the tuner analyzes sound in device memory to estimate frequency and provide tuning feedback. Audio is not saved or uploaded. Capture stops when you leave the tuner or the app enters the background. The metronome and reference tones play locally synthesized sound without recording. You can revoke microphone access in system settings.

Optional iCloud sync

iCloud sync on iPhone is enabled by default. When your system iCloud account and network are available, Apple CloudKit synchronizes completed practice records, including entered content, times, revisions and deletion markers, to that account’s private database. An account identifier and sync progress are stored locally to prevent mixing data from different accounts. Frettio does not require a separate account or obtain your Apple account password.

The library links to the first available iCloud account. Sync pauses if you change accounts and can resume with the original account. Active timers, the project library, tuning presets and tool preferences are not uploaded through this cloud sync. Turning sync off stops subsequent transfers without deleting existing local or cloud data. Turning it back on resumes pending work. Sync is not an instant backup and depends on system conditions, connectivity and storage. System device backups are separate and controlled by your system settings.

iPhone and Apple Watch

Paired devices use Apple WatchConnectivity to transfer tuning presets, ordered practice projects, project durations, the default duration and recent durations. Completed Watch practice records are sent to iPhone and acknowledged after the phone saves them. Records on iPhone may then participate in enabled iCloud sync.

When using a phone system alarm, the Watch also sends reminder plans (identifiers, deadlines, state and revisions) and cancellation requests to iPhone, which returns the scheduling result. This contains no recording and does not synchronize the full active timer session. Delivery can be delayed when devices are disconnected.

Notifications and alarms

Completion reminders request notification permission when needed. Choosing system alarms on iOS 26 or later separately requests AlarmKit authorization. Denying permission does not prevent timing or saving but affects reminders. Watch local notifications remain available; phone alarms depend on successful delivery and scheduling. You can change reminder preferences and permissions in the app and system settings.

Network services, external links and this website

Version checks send the app identifier and storefront region to Apple’s lookup service, not your practice content. StoreKit provides the storefront region to select relevant app links; this is not location tracking. Opening the App Store, Rednote or your email app is subject to those services’ policies.

This website is hosted on Cloudflare Pages. Cloudflare may process IP addresses, request times, browser information and other request data to deliver and secure the website. This site uses no advertising, analytics scripts, forms or tracking cookies. See the Apple Privacy Policy and Cloudflare Privacy Policy for their practices.

Deletion, retention and contact

Deleting a practice removes it from lists and statistics. To prevent an offline device from uploading an old copy again, the device and enabled iCloud sync retain a full record snapshot with a deletion marker, including original content and revisions. There is currently no automatic expiry or restore feature. In-app deletion therefore does not immediately erase every copy. Avoid entering unnecessary sensitive information in practice projects.

Uninstalling removes that device’s local app data, but does not automatically remove copies on a paired device, in iCloud or in system backups. For cloud or backup removal, check Apple’s iCloud storage management; available controls depend on the system. Removing cloud data may pause local sync. The developer cannot access your private iCloud records on your behalf; contact us for guidance on available removal options.

Your email address, messages and attachments voluntarily sent to support are used to handle your request and necessary follow-up, not advertising. Avoid sending sensitive content. You may request access, correction or deletion of support correspondence we hold. We retain it for the time needed to handle requests and meet applicable legal obligations. Children should use the app with a guardian’s guidance. Contact us if a child has submitted personal information to us.

Policy updates

We will update this page and relevant App Store privacy information when features or data practices change. New uses requiring authorization will be explained and consent requested as applicable. For privacy or support questions, contact the email above.

隐私政策

更新日期:2026 年 11 月 7 日

本政策适用于 Frettio 的 iPhone 与 Apple Watch 应用,以及本协议网站。Frettio 由独立开发者维护,用于练习记录、调音、节拍和吉他资料查询。隐私联系邮箱:support@cocoboloa.com。

设备上的数据

练习记录(日期、时长、项目内容及修改)、正在进行的计时和恢复信息、练习项目、常用时长、调弦方案及偏好保存在设备内。我们没有自建账号或用于接收练习记录、音频的业务服务器,不接入广告、跨应用追踪或第三方分析 SDK。

麦克风与声音

调音器在获得麦克风授权后,将声音在设备内存中实时分析为频率,用于调音反馈;不保存或上传音频。离开调音器或 App 进入后台会停止采集。节拍器与参考音只播放本地合成声音,不需要录音。可随时在系统设置撤销麦克风权限。

可关闭的 iCloud 同步

iPhone 的 iCloud 同步默认开启,在系统 iCloud 账号和网络可用时,通过 Apple CloudKit 将已完成的练习记录(包括填写的内容、时间、修订信息及删除标记)同步到该账号的私有数据库。同步用的账号标识及进度保存在本机,以避免将不同账号的数据混合。Frettio 不要求单独注册账号,开发者不会通过 App 获取你的 Apple 账号密码。

资料库关联首次可用的 iCloud 账号;更换账号时暂停同步,切回原账号可继续。正在进行的计时、项目库、调弦方案和工具偏好不通过此云同步上传。关闭同步会停止后续收发,但不会删除已有本地或云端数据;重新开启会继续待处理的同步。同步并非实时备份,可能受系统、网络或可用空间影响。系统设备备份是独立机制,由你的系统设置控制。

iPhone 与 Apple Watch

配对设备通过 Apple WatchConnectivity 传输调弦方案、练习项目及顺序、项目时长、默认时长和常用时长。手表完成的练习会发送给手机,并在手机保存成功后确认送达。手机上的记录随后可参与已开启的 iCloud 同步。

选择由手机系统闹钟提醒时,手表还会向手机发送练习提醒计划(标识、截止时间、状态与修订)及取消请求,手机返回排定结果。此传输不包含录音,不是完整的进行中计时会话同步;设备断连时可能延迟。

通知与闹钟权限

到期提醒按需请求通知权限;选择 iOS 26 或更新系统的系统闹钟方式时,另行请求 AlarmKit 授权。拒绝权限不会阻止计时和保存,但会影响提醒。手表保留本地通知,手机闹钟依赖成功接收并排定计划。可在 App 偏好和系统设置调整这些权限与提醒方式。

联网、外部链接与本网站

版本检查通过 Apple 的查询服务发送 App 标识与商店地区,不发送练习内容。商店地区由 StoreKit 读取,用于选择相关应用链接,不等同于位置定位。打开 App Store、小红书或支持邮箱后,相应服务按自己的政策处理数据。

本网站由 Cloudflare Pages 托管。访问时,Cloudflare 为提供网络服务及安全防护可能处理 IP 地址、请求时间、浏览器信息等网络请求数据。本网站没有广告、分析脚本、表单或用于追踪的 Cookie。Apple 和 Cloudflare 的处理规则分别见 Apple 隐私政策及 Cloudflare 隐私政策。

删除、保留与联系

删除练习会将其从列表和统计移除。为防止离线设备重新上传旧记录,本机与已开启同步的 iCloud 中会保留带删除标记的完整记录快照,包括原练习内容及修订;当前没有自动到期清理或恢复入口。因此,App 内的“删除”不等同于立即彻底擦除所有副本。不要在练习项目中填写不必要的敏感信息。

卸载 App 会移除该设备的 App 本地数据,但不会自动删除配对设备、iCloud 或系统备份中的副本。需要清理云端或备份时,请检查 Apple 提供的 iCloud 存储管理;其可用选项以系统为准。云端数据被移除后,本机同步可能暂停。开发者不能代你访问私有 iCloud 记录;可通过邮箱咨询适用的清理方式。

你主动发给支持邮箱的地址、文字及附件仅用于处理请求与必要的后续沟通,不用于广告。请避免提交敏感内容;可联系我们请求访问、更正或删除我们持有的支持通信。我们按处理请求所需的期限及适用法律要求保留这些通信。儿童应在监护人指导下使用;如发现儿童向我们提交了个人信息,请联系处理。

政策更新

功能或数据处理发生变化时,我们会更新本页和必要的 App Store 隐私信息。涉及需要授权的新增用途时,会按适用要求另行说明并征求同意。隐私或支持问题请联系上方邮箱。
