This policy explains how Fenglan Xingchen (shanghai) Artificial Intelligence Technology Co., Ltd ("we" or "us") handles personal information when providing the Evolve Hospitality mobile apps (易服智能; the current English app display name is Easyserve), and how you can exercise your rights. Please read this policy before using the app.
Scope and processing roles
This policy applies to the iOS, Android and HarmonyOS apps, a customer service, work order and operations collaboration tool for employees authorized by hotels or other enterprises. Public self-registration is not available.
We process information needed to provide employee accounts, secure operations and technical support. For guests, channel customers, reservations, chats, work orders and housekeeping information, your hotel or enterprise generally determines the purposes and access permissions. We provide technical services under its authorization and instructions. You should also read and follow your organization's internal privacy and data-use rules.
Information we process
Employee accounts and permissions
Account identifiers, names, telephone numbers, profile images, hotel or enterprise affiliation, roles, menu permissions, work order groups, and sign-in and session authentication information. Enterprise administrators create, configure and deactivate accounts.
Hotel business and customer service
Depending on enabled features, this may include guest or channel-customer names, contact details, profile images, reservations and stay information, room numbers, service preferences, identity-verification information, chat text and images, work orders, attachments, processing statuses and action records. The actual scope depends on enterprise configuration and your access permissions.
Devices and operation
To maintain sessions, protect security and troubleshoot problems, we may process device platform and version, network addresses, sign-in times, action logs and errors. Some earlier versions do not provide system push; versions that support push may, after you consent and allow notifications, process Apple or device-vendor push tokens, JPush registration identifiers, device, system and network information and delivery records to associate a device with your current account and organization and deliver notifications. Notifications may contain customer message or work order previews. We do not separately retain in-app search history long term.
Support requests
When you contact us, we process information you choose to provide, including your name, contact details, organization, issue description, screenshots and necessary diagnostics. Redact guest personal information unrelated to the issue before submitting it.
Purposes of processing
- Verify employee identity, restore sessions and control access by role and organization.
- Display and process authorized chats, work orders, reservations, housekeeping and operational information.
- Connect customer service channels, hotel systems, messaging services and business tools configured by your organization.
- Display authorized chats, work orders and system messages in the app and, if enabled, deliver customer message and work order notifications to authorized devices in the current organization.
- Troubleshoot problems, prevent abuse and protect accounts, networks and services.
- Respond to support, access, correction, deactivation or deletion requests.
- Meet applicable legal, regulatory or dispute-resolution obligations.
We do not use this information for advertising profiles or transactions unrelated to your organization's authorized purposes.
Retention, location and security
Business data is retained for the period agreed with each enterprise customer, subject to applicable legal requirements. Ask your administrator for your organization's retention period. Account deactivation does not automatically delete enterprise business records. At the end of the agreed period, deletion, anonymization or legally required retention is handled under the agreement and applicable law.
The enterprise retention period does not establish zero retention by Bailian. Bailian stores model and application invocation data as required by law. Provider records and cloud logs are governed by applicable service terms, settings and retention rules, separately from our business database. We do not promise immediate deletion of all backups.
Push registrations are used while the service is enabled. When you sign out, switch organizations or withdraw push consent, we attempt to deactivate the registration and retry later if offline or unsuccessful. A notification preview may be encrypted in the pending delivery queue for retries and is removed from the task on success or cancellation. Backups and provider records may remain under their own rules; contact your organization or us for details. Jiguang's processing and retention are described in its privacy policy. Notifications already submitted to a provider cannot necessarily be recalled immediately.
Security measures include encrypted transmission, platform secure storage, role- and organization-based access controls, sensitive-information masking and action logs. No system can guarantee absolute security. If an incident may affect your rights, we will take response and notification measures required by law.
If processing involves international transfers, we will complete the assessments, notices, authorizations or other compliance procedures required by applicable law.
Your rights and choices
To the extent provided by applicable law, you may request access, copies, correction, supplementation, restriction or deletion of your information, and withdraw consent for processing based on consent.
- Accounts and roles: contact your enterprise administrator first. Accounts are enterprise-created, not publicly self-registered. Administrators deactivate or delete accounts when employees leave, change roles or stop using the service.
- Guest and business data: contact the hotel or enterprise determining the processing purposes. We provide technical assistance after verifying its authorization.
- Notifications: in versions supporting push, use More → Message Notifications to enable, disable or withdraw push consent and choose whether to send message and work order previews. Without preview consent, only generic alerts are sent. You can also disable notifications in your device settings. Adjust system notification settings to hide previews when locked; on iPhone, select When Unlocked. In-app chats and work orders remain available without push.
- Privacy requests: email info@vastbluestarry.ai. To protect accounts and enterprise data, we may verify your identity, organization and authority to make the request.
Minors
The app is a business tool for enterprise-authorized employees. It does not offer services to minors or target minors when creating accounts. Contact us if you discover a minor's information submitted without appropriate authorization.
Updates and contact
We may update this policy when features, processing practices or applicable laws change. Material changes will be communicated through the app, website or a channel accessible through your organization, and the page will show the updated date.
