Privacy Policy for the “HeyClient” App and Website
Last updated: October 2025
1. Scope and Quick Overview
These privacy notices explain how personal data are processed when you use the mobile app “HeyClient” (the App) and our Website (the Website).
App (short): The App reads your contacts locally on your device, detects birthdays/holidays, shows local notifications, and creates personalised message drafts. Messages are sent only after your confirmation via WhatsApp/SMS/email (deep links: wa.me, sms:, mailto:).
The App has no server connection: no transmission to us, no tracking, no external storage.
Website (short): On the Website we use — based on consent — cookies/tracking and the following services: Google Analytics 4 (optional: Signals/User-ID), Google Tag Manager, YouTube (two-click solution), Meta/Facebook Pixel, LinkedIn Insight Tag, Twitter/X Pixel, and (where offered) newsletter and contact forms.

3. Legal Bases (Overview) and Access to End-User Devices
Art. 6(1)(b) GDPR (Contract performance): provision of App functionalities.
Art. 6(1)(a) GDPR (Consent): optional App/Website features (e.g., notifications, analytics/marketing cookies). You can withdraw consent at any time.
Art. 6(1)(f) GDPR (Legitimate interests): e.g., IT security, Website stability.
Section 25(2) No. 2 TDDDG (Germany): access/storage on your device that is strictly necessary to provide a service you expressly requested (App functionality, strictly necessary cookies).
(The App itself does not use cookies or comparable technologies.)
4. Private Use (“Household Exemption”)
If you use HeyClient exclusively for private or family purposes (e.g., congratulating friends/family), your use is generally outside the scope of the GDPR (Art. 2(2)(c) GDPR).
If you use the App in a business/professional context (e.g., messages to customers), you are a controller under the GDPR and must ensure a legal basis (e.g., consent or legitimate interests) and fulfil information duties. Regardless, we process data for the Website and any other offerings as set out in this policy.

Contact data: name, nickname (if any), birthday (if stored), email address(es), phone number(s).
Local App usage data: templates (with placeholders), settings (e.g., notifications), times of local reminders.
Message drafts: locally created, personalised texts.
