Behavioral Advertising
Xder offers a free version partially funded by advertising.
Our objective is that advertising never compromises user privacy, safety, or social experience.
Xder does not sell your name, phone number, email address, or message content to advertisers.
1. Types of advertising in Xder
Xder uses three distinct advertising modes:
1.1 Contextual advertising (default mode)
Based only on:
the section you are currently using
language
approximate country
It does not use behavioural history.
1.2 Personalised advertising (consent required in EU/UK)
May use advertising identifiers to display general interest-based ads.
It is never based on:
chat content
sexual orientation
gender identity
intimate preferences
sensitive profile data
1.3 Measurement and attribution
Used only to:
understand whether you installed the app from an ad
prevent advertising fraud
It does not personally identify you.
2. Your control and service neutrality
You can change your choice at any time:
Settings → Privacy → Ad Preferences
Guarantees:
Rejecting personalised ads does not reduce visibility
Does not affect matching algorithms
Does not limit features
Does not degrade user experience
Xder does not penalise users for exercising privacy rights.
3. Identifiers used and technical safeguards
We may use:
IDFA (Apple)
GAID (Android)
partially anonymised IP
anti-fraud event signals
Fingerprinting prohibition
Xder contractually forbids partners from:
using device fingerprinting techniques (battery level, sensors, fonts, display characteristics, hardware configuration or similar) to identify users who opted out of tracking.
Additional protections
truncated IP
identifier rotation
data minimisation
Identifiers can be reset in your device settings.
4. Xder advertising on external platforms
We promote Xder on platforms such as Meta, TikTok, and mobile ad networks.
In these cases:
only encrypted identifiers are shared
profiles are never shared
photos are never shared
chats are never shared
5. Transparency and advertising partners
We maintain an updated list of advertising and measurement providers available in the:
Privacy Preference Center inside the app
We periodically audit partners to ensure compliance with privacy standards.
6. International privacy standards
Xder applies:
IAB Europe Transparency & Consent Framework (TCF)
GDPR (EU)
UK GDPR
Global Privacy Control signal (when technically available)
7. Notifications and delivery infrastructure
To deliver notifications we use:

These providers process technical delivery data under their own privacy policies.
8. Advertising on the website
Our website may use advertising cookies.
You can manage them through the permanent link:

Rejecting them does not prevent using the site.
9. Sensitive category protection
Xder prohibits advertising segmentation based on sensitive categories, even with consent, including:
health
religion
political affiliation
sexual life
personal financial situation
We also prohibit partners from using Xder-derived data to advertise:
loans

medical services
personalised financial products
10. Artificial intelligence and advertising
Xder automated systems:
do not train advertising models using private conversations
do not store messages for ad learning
operate only on aggregated technical signals
11. Privacy guarantees (What we never do)
Xder does not:
sell personal data to data brokers
share data with affiliated apps for cross-marketing without consent
use sexual orientation for ad targeting
allow retargeting based on intimate activity
allow financial or medical profiling
degrade service quality if ads are declined
12. Withdrawal of consent

After withdrawal:
personalisation stops
only minimal anti-fraud logs remain
