Global Scope: The research spanned continents, including Brazil, India, the Netherlands, New Zealand, the Republic of Korea, and the U.S., uncovering vast differences in pricing strategies within and across these regions.
Key Findings:
Age-Based Pricing Discrepancy: Tinder's pricing algorithm considers user data such as age, resulting in discriminatory "differential pricing" based on age, race, gender, and sexual orientation. The study revealed stark pricing differences based on age, with users between 30-49 years old being charged an average of 65.3% more than those aged 18-29.
Diverse Pricing: The study, spanning 5 continents, identified as many as 31 different price points for Tinder Plus, with users charged significantly different amounts for identical services. In the Netherlands, Tinder Plus prices ranged from $4.45 to $25.95, while in the U.S., the range was from $4.99 to $26.99, indicating significant variability in the same country.
Price Variations and Consumer Reaction: The discovery of up to 31 different price points for the same service within a single country raised concerns among consumers about the fairness and transparency of Tinder's pricing model.
Legal Implications:
Potential Age Discrimination: The pricing strategy raises potential legal issues under laws such as the Australian Age Discrimination Act 2004 and the UK Equality Act 2010, which protect against unfair treatment based on age.
Challenge in Pricing Justification: Legal experts argue that differential pricing based on age requires justifiable reasons, especially under anti-discrimination laws.
Tinder's Response:
Discount Acknowledgment: Tinder acknowledged offering "discounted subscriptions" to younger users but provided limited details about the criteria or justification for these discounts.
Response to Pricing Queries: Despite inquiries and legal challenges, Tinder's responses have been limited in addressing the specific reasons behind their varied pricing model.
Legal History:
Age Discrimination Lawsuit in California: Tinder faced a lawsuit in California with a settlement of $24 million for charging users over 28 years old double the amount compared to younger users.
Settlement Reversal and Policy Change: Following the 9th Circuit's reversal of the settlement in August 2021, Tinder announced plans to discontinue age-based discounts in future pricing strategies.
User Concerns:
Survey Insights: A consumer survey related to the study showed that 97% of respondents were concerned about personalised pricing, and 83% supported having the choice to opt out of such pricing models.

Definition and Importance: Inclusivity in design ensures that technology is accessible to people of all ages, races, genders, abilities, and identities. The Inclusive Design Research Centre (IDRC) defines it as considering the full range of human diversity.
Application in Age-Related Design: Inclusivity means creating digital tools that cater to various age groups without biases or stereotypes. This approach opposes discriminatory practices, ensuring that technologies serve everyone equitably, regardless of age.
Fairness:
Fair Distribution and Participation: Fairness in design involves the equitable distribution of benefits and burdens, ensuring meaningful participation in design decisions, and recognising community-based traditions and practices.
Case Study Application: In the context of Tinder's pricing algorithm, fairness would entail charging all users equally, using impartial algorithms that don't discriminate based on characteristics like age. Fair design ensures equal access to app features for all users.
Accessibility:
Ensuring Universal Access: Accessibility emphasises the need for technology to be usable by all, regardless of abilities or financial status. It's about aligning the design or system with the individual's requirements, often a legal obligation.
Implications for Tinder: In the case of Tinder, accessibility means providing equal access to the app’s features and functions for all users, regardless of age or financial capability.
Intersectionality:
Understanding Compound Discrimination: Intersectionality recognizes that individuals experience multiple forms of discrimination simultaneously, such as ageism, sexism, racism, and ableism.
Relevance in Tinder's Case: For Tinder, considering intersectionality is vital, as older users, especially those belonging to other marginalized groups, may face amplified discrimination. An inclusive algorithm should avoid perpetuating discrimination based on various identity aspects.
Accountability and Transparency:
Responsibility of Designers: Designers and developers are accountable for the societal impact of their work. Accountability would require entities like Tinder to take responsibility for any discriminatory impacts of their algorithms.
Need for Openness: Transparency involves making design processes and decisions clear to all stakeholders. For Tinder, this means disclosing how prices are determined, including any age-related factors, allowing users to make informed decisions about purchasing premium services.
Recommendations: Addressing Tinder's Age-Related Unfair Pricing
