Zero Data Sales: Why It Matters for Family Location Tracking
A zero-data-sales policy is a commitment by a service provider to never sell, share with advertisers, or monetize personal information — including GPS location data — in any form. For family location tracking apps, this policy is the single most important privacy protection a platform can offer, because precise location data is among the most sensitive categories of personal information and, once sold, cannot be recalled, deleted, or controlled.
When a family tracking app sells your data, your child's daily routines — the school they attend, the times they leave home, the routes they take, the places they spend time — become a commodity traded between data brokers, advertisers, and analytics firms you have never heard of and never consented to share with.
What Happens When Location Data Is Sold
The journey of sold location data typically follows a chain:
The tracking app collects GPS coordinates from your child's device. Each data point includes latitude, longitude, timestamp, speed, and often device identifiers.
The app transmits data to a data broker — either directly or through an intermediary analytics partner. The data broker aggregates location information from thousands or millions of devices into a searchable database.
The data broker packages and resells the data to clients including advertisers, hedge funds, real estate developers, insurance companies, law enforcement agencies, and other data brokers further down the chain.
End buyers use the data for purposes that may include targeted advertising, competitive intelligence, surveillance, risk assessment, and profiling. A 2024 FTC enforcement action revealed that one major data broker was selling location data precise enough to track individuals to specific medical facilities, places of worship, domestic violence shelters, and addiction treatment centers.
Once your data enters this chain, there is no mechanism to recall it. Deletion requests to the original app do not propagate through the broker network. Your family's movement history exists in databases you cannot access, operated by companies you cannot contact, used for purposes you cannot control.
The Scale of the Location Data Market
The location data industry is enormous. Industry estimates place the global location intelligence market at over $20 billion annually, with mobile app data as a primary source.
A single smartphone generates thousands of location data points per day. For a family tracking app monitoring multiple devices continuously, the data output is substantial — and valuable. Location data enriched with behavioral patterns (daily routines, commute times, frequented locations, weekend activities) commands premium pricing in the broker market.
The economic incentive is significant: a family tracking app with one million users generating continuous location data can earn millions of dollars annually from data sales alone, dwarfing potential subscription revenue. This is why many tracking apps offer their services for free or at heavily subsidized prices — the real revenue comes from your data, not your subscription.
Why "Anonymized" Location Data Is Not Anonymous
Companies that sell location data frequently claim the data is "anonymized" or "de-identified" before sale. This claim is misleading for location data specifically.
A 2019 study published in Nature Communications demonstrated that four location data points are sufficient to uniquely identify 95% of individuals in a dataset of 1.5 million people. The researchers showed that knowing just four places a person visited — and the approximate times — was enough to distinguish them from everyone else in the dataset.
The reason is intuitive: your home address and your workplace, visited daily at predictable times, form a nearly unique fingerprint. Add the school your child attends and the sports facility where they practice, and re-identification becomes trivial.
This means that a data broker receiving "anonymized" location data from a family tracking app can, with minimal effort:
- Identify your home address (where devices rest overnight)
- Identify your child's school (daytime location on weekdays)
- Identify after-school activities and their locations
- Map your family's social network based on frequent visit locations
- Determine your family's daily schedule with hour-by-hour precision
"Anonymous" location data, in practice, is not anonymous at all. The FTC has explicitly stated that it considers location data to be identifiable personal information even when names and other identifiers are removed.
Real-World Harms From Location Data Sales
The consequences of location data sales are not hypothetical. Documented harms include:
Physical safety risks. Domestic violence survivors whose locations are sold through tracking apps face direct physical danger. Data broker databases do not distinguish between a routine user and a person whose location must remain confidential for their safety.
Child safety risks. Location data showing a child's school, travel routes, and after-school activity schedule creates a detailed pattern of a minor's daily movements. This data, available for purchase without verification of the buyer's identity or intent, poses obvious risks.
Stalking and harassment. The FTC has documented cases where individuals purchased location data to stalk former partners, monitor specific people, and harass individuals at their homes and workplaces.
Insurance and employment discrimination. Location data revealing visits to medical facilities, therapy offices, or support groups can be used for discriminatory purposes — even when such use is technically prohibited by law, enforcement is difficult when the data has already been disseminated.
Government surveillance without warrants. Law enforcement agencies have purchased location data from commercial brokers to track individuals without obtaining a warrant, effectively bypassing Fourth Amendment protections. The U.S. Court of Appeals has issued rulings addressing this practice, but the legal landscape remains contested.
How to Identify Apps That Sell Your Data
Not every tracking app is transparent about its data practices. Use these signals to assess whether an app monetizes your family's data:
The Price Signal
If a full-featured family tracking app is completely free, ask how it generates revenue. Legitimate free services (like Apple's Find My) are subsidized by hardware sales. Standalone free tracking apps with no obvious revenue source are almost certainly monetizing data.
The Privacy Policy Test
Search the privacy policy for these terms:
- "Third-party partners": Who are they? If unnamed, assume data brokers and advertisers.
- "Aggregated data": This is the most common vehicle for location data sales. As discussed above, aggregated location data is trivially re-identifiable.
- "Improve services": When improving services requires sharing data with unnamed external parties, that is data monetization.
- "Analytics partners": Analytics companies frequently act as intermediaries between apps and data brokers.
- "Advertising": Any mention of advertising in a family tracking app's privacy policy is a red flag. Location-based advertising requires sharing location data with ad networks.
The Permission Test
When you install the app, what permissions does it request? A location tracking app needs GPS access. It does not need access to your photos, microphone, camera, or advertising identifier. Excessive permissions suggest data collection beyond what the service requires — typically for monetization purposes.
What a Meaningful Zero-Data-Sales Policy Looks Like
A genuine zero-data-sales policy should be:
Explicit. Not "we value your privacy" — but "we never sell personal information to any third party."
Comprehensive. Covering all categories of data (location, contacts, device metadata), all forms of sharing (sale, exchange, licensing), and all recipients (advertisers, data brokers, analytics firms, partners).
Unconditional. Not "we do not sell your data unless..." There should be no exceptions for aggregated data, de-identified data, or data shared with "trusted partners."
Verifiable. The company should name its subprocessors (the third parties that handle data on its behalf) and explain the purpose of each relationship. If the only third parties are infrastructure providers (cloud hosting, payment processing), that is consistent with a zero-data-sales policy. If the list includes analytics or advertising companies, it is not.
Jussive maintains a zero-data-sales policy that meets all four criteria. Family location data is never sold to third parties, shared with advertisers, or monetized in any form. The platform's subprocessors are limited to infrastructure providers: AWS for hosting and compute, Stripe for payment processing, and Apple and Google for app distribution. All data is encrypted with AES-256 at rest and TLS 1.2+ in transit, and belongs exclusively to the family account holder.
The Business Model Behind Zero Data Sales
When a family tracking app commits to zero data sales, it means the company's only revenue source is subscriptions. This creates an economic alignment between the company and its users that is fundamentally different from the ad-supported or data-monetization model.
In a subscription model:
- Your data is a liability, not an asset. The company has every incentive to minimize data collection, secure what it holds, and delete it when it is no longer needed.
- Your trust is the product. The company succeeds when users renew their subscriptions, which only happens when users trust the service.
- Retention depends on privacy. A breach, a data sale scandal, or a privacy policy change would directly threaten revenue. The company's financial survival depends on maintaining the zero-data-sales commitment.
Compare this to a data monetization model, where:
- Your data is the primary product. The company's revenue increases with more data collection, longer retention, and broader sharing.
- Users are the supply chain. Your family's location data has more value to the company when sold than when protected.
- Privacy improvements reduce revenue. Any restriction on data collection or sharing directly impacts the bottom line.
The business model is the most reliable indicator of a company's actual data practices. Policies can be changed; economic incentives are structural.
How Zero Data Sales Interacts With Other Privacy Protections
A zero-data-sales policy is the foundation, but it works best in combination with other privacy protections:
COPPA compliance ensures that data from children under 13 is collected only with verifiable parental consent and can be deleted at any time. See our COPPA compliance guide for details.
Encryption (AES-256 at rest, TLS 1.2+ in transit) ensures that even if data is accessed improperly, it cannot be read. For a deeper understanding of how encryption protects family data, see our guide on data privacy in family tracking apps.
Defined data retention limits the window of exposure. Data that is deleted after 7, 30, or 90 days cannot be breached after the retention period expires.
Parental control over data means the account holder can pause monitoring, modify what is collected, and permanently delete all data at any time. This right is meaningless if data has already been sold to a third party — which is why zero data sales is the prerequisite that makes all other privacy controls effective.
Making an Informed Choice
When evaluating family tracking apps, put the data-sales question first. Before comparing features, pricing, or user interface, determine whether the platform sells your data. If it does, no other feature compensates for that foundational compromise.

Frequently Asked Questions
If an app says it shares "aggregated" data, is that the same as selling my data?
In practice, yes — especially for location data. Aggregated GPS coordinates can be re-identified with as few as four data points. When a company shares "aggregated" location data with third parties, your family's movement patterns are effectively being disclosed, even if your name is not attached. A meaningful zero-data-sales policy prohibits sharing data in any form, including aggregated or de-identified formats.
Do paid apps ever sell data too?
Yes. A subscription fee does not automatically mean the company is not selling data. Some apps charge a subscription and sell data. The key indicator is the privacy policy, not the pricing model. Look for an explicit, unconditional zero-data-sales commitment. However, the economic incentive is stronger for subscription-only companies to protect data, since trust directly drives revenue.
Can I get my data back once it has been sold to a data broker?
No. Once data enters the broker ecosystem, it is copied, redistributed, and resold across a network of companies. Deletion requests to the original app do not propagate through this chain. Most data brokers have no mechanism for consumers to request deletion of specific records, and even when they do, the data may have already been resold further. Prevention — choosing a platform that never sells data — is the only reliable protection.
How does Jussive make money if it does not sell data?
Jussive operates on a subscription model at $7.99 per month. All revenue comes from user subscriptions. The company does not sell data, display advertising, or monetize user information in any form. This business model aligns the company's financial incentives with protecting user data.
Is a zero-data-sales policy legally binding?
A company's privacy policy is a legally enforceable document. If a company commits to never selling data in its privacy policy and then sells data, it has violated its own terms — which can trigger enforcement actions by the FTC and state attorneys general under consumer protection laws. Deceptive privacy practices (saying one thing and doing another) are among the most aggressively prosecuted violations in the privacy enforcement landscape.
