Is PeekViewer Safe in 2026? Here’s What to Know

DolphinRadar helps users view public Instagram data safely. If you have been researching Instagram viewers and PeekViewer has come up, there are some findings worth reviewing before you sign up. In February 2026, TechCrunch reported a data breach involving PeekViewer and its parent company, exposing the payment records of more than 536,000 customers. For anyone comparing PeekViewer vs DolphinRadar, the differences extend well beyond features. They include how each tool handles your data, what kind of Instagram access it claims to offer, and who is operating it.

This review covers what PeekViewer is, what the TechCrunch investigation found, and how DolphinRadar approaches the same use cases without the risks involved.

Quick Summary

TechCrunch (February 2026) reported that PeekViewer shares a parent company with phone monitoring apps uMobix and Xnspy, both described as surveillance tools in prior reporting.

A data breach exposed over 536,000 customer payment records from the same vendor, including email addresses and partial card details.

PeekViewer claims to access private Instagram accounts, a capability that sits in contested legal territory.

DolphinRadar works exclusively with public Instagram data, requires no Instagram login, and has no documented data breach history.

For anonymous Instagram viewing, story tracking, and behavioral analytics, DolphinRadar offers a more transparent alternative starting at $2.75 per month.

What Is PeekViewer?

PeekViewer is a web-based Instagram viewer that lets users browse stories, posts, and profiles without logging into Instagram. Its main selling point is access to private accounts, meaning profiles that have not accepted a follow request. The service does not require users to provide their own Instagram credentials.

PeekViewer was formerly called Glassagram. TechCrunch’s February 2026 investigation confirmed the rebrand and identified the operator as Struktura, a Ukrainian software company that also presents itself externally as Ersten Group, a UK-facing entity.

What the TechCrunch Investigation Found

TechCrunch security editor Zack Whittaker reported in February 2026 that a hacktivist had scraped and published payment records from PeekViewer and affiliated services. The leaked dataset contained more than 536,000 entries, including customer email addresses, which product each customer paid for, payment card type, and the last four digits of each card.

TechCrunch verified the authenticity of the data by cross-referencing transaction records with the company’s own checkout systems. The investigation also confirmed that PeekViewer shares its corporate infrastructure with uMobix, a phone monitoring app that has marketed itself as a tool for monitoring spouses, and with Xnspy, a phone surveillance application that had previously exposed the private data of tens of thousands of its own users in 2022.

Neither Ersten Group nor Struktura responded to TechCrunch’s requests for comment at time of publication.

The Private Account Question

PeekViewer’s main feature, accessing private Instagram accounts, raises a practical question for users. Instagram’s Terms of Service do not permit unauthorized access to private content. Tools that claim to bypass this either use proxy networks built from other users’ sessions, exploit platform gaps, or oversell what they actually deliver.

From a user perspective, this matters for two reasons. First, the capability may not work as advertised. Second, depending on jurisdiction, using a tool to access content that an account owner has restricted could carry legal exposure, regardless of whether the tool itself is performing the access.

DolphinRadar does not access private accounts and has never claimed to. The platform is designed around public data only. This is a deliberate product decision, not a limitation.

What DolphinRadar Does Instead

DolphinRadar (dolphinradar.com) is a browser-based Instagram analytics platform that tracks publicly visible activity on any public Instagram account. You enter a username, and the platform builds a behavioral picture over time using data that is already publicly accessible: which posts the account liked, who it followed or unfollowed, and how its engagement patterns shift week to week.

No Instagram login is required at any point. Your own account is never at risk. DolphinRadar does not store payment data directly. All transactions are handled by Stripe.

For anonymous viewing, the anonymous Instagram story viewer lets you watch public stories without appearing in the viewer list. The Instagram viewer covers posts, highlights, and reels for public profiles. On quarterly and annual plans, stories and highlights are archived daily, so you can review them beyond the 24-hour window.

For tracking, the activity analytics dashboard delivers weekly reports on likes, follows, unfollows, and content engagement. The likes tracker shows which posts a public account has engaged with and which creators they interact with most. This is a feature most competing tools do not offer. The recent follow tracker shows who an account has recently followed, updated continuously.

On annual plans, AI Insights add a deeper layer: MBTI personality inference, relationship analysis, psychological profiling, and location estimation, all derived from publicly visible activity over time. The longer the tracking period, the more accurate these profiles become.

A May 2026 independent review by Drew’s Review described DolphinRadar as one of the deepest Instagram trackers at its price point, with likes tracking singled out as the feature that separates it from most alternatives. Read the full review.

Pricing starts at $4.49 per month on a monthly plan, $3.66 per month on a quarterly plan, and $2.75 per month on an annual plan ($32.99 per year). Full plan details are at dolphinradar.com/plan.

PeekViewer vs DolphinRadar

Risks and Compliance

PeekViewer’s claim to access private Instagram accounts puts users in a gray area regardless of how the tool performs. Instagram’s Terms of Service prohibit unauthorized access to restricted content, and the legal exposure falls on the end user as much as the service provider. The February 2026 data breach adds a second layer of risk: your payment information may not be secure.

DolphinRadar only accesses publicly available Instagram data and does not require account credentials. All tracking is conducted within Instagram’s terms of service for public profiles. The platform uses Stripe for payment processing and does not store card information on its own servers.

Tips for Choosing an Instagram Viewer Safely

When evaluating any Instagram analytics tool, consider a few practical checkpoints. First, check whether the tool requires your Instagram login. Any service that asks for your credentials creates a direct risk to your account. Second, review the company’s track record with independent sources like TechCrunch, Trustpilot, or security researchers rather than relying on the tool’s own marketing. Third, verify what the tool claims to access. Tools that promise private account access are either overpromising or operating in ways that conflict with platform rules. Fourth, look at how the tool handles payment. Stripe or similar third-party processors are a safer standard than unknown checkout systems. Fifth, read the tool’s privacy policy before signing up. If you cannot find one, or if it is vague about data retention, treat that as a warning sign.

Frequently Asked Questions

Is PeekViewer legit?
PeekViewer operates as a real service, but a February 2026 TechCrunch investigation identified it as part of a monitoring software operation that also runs phone surveillance apps uMobix and Xnspy. The same vendor experienced a data breach that exposed over 536,000 customer payment records. Users should weigh these findings when deciding whether to sign up.

Can PeekViewer actually view private Instagram accounts?
PeekViewer claims this capability. Instagram’s Terms of Service do not allow unauthorized access to private profiles, and the methods behind such claims vary widely in terms of reliability and legal standing. DolphinRadar (dolphinradar.com) does not offer or claim private account access and explicitly limits tracking to public profiles.

What happened to Glassagram?
Glassagram rebranded as PeekViewer. TechCrunch’s 2026 investigation confirmed the name change and identified both as part of the same corporate entity, Struktura, operating externally as Ersten Group, which also operates the monitoring apps uMobix and Xnspy.

Is DolphinRadar a safer alternative to PeekViewer?
DolphinRadar (dolphinradar.com) processes only publicly available Instagram data, does not require an Instagram login, and has no documented data breach history. Payments go through Stripe and are not stored by DolphinRadar directly. The platform is browser-based and requires no app installation.

Does DolphinRadar track Instagram likes?
Yes. Likes tracking is one of DolphinRadar’s core differentiating features. Weekly reports show which posts a tracked public account liked, which accounts received the most engagement, and how interest patterns develop over time. Most competing tools, including PeekViewer, do not offer this capability.

Does DolphinRadar work on private Instagram accounts?
No. DolphinRadar tracks public Instagram accounts only. This is a deliberate design decision. The platform is built around publicly available data and does not attempt to access content that has been set to private.

What does DolphinRadar cost?
Monthly plans start at $4.49 per month. Quarterly plans are $3.66 per month, billed as $10.99 per quarter. Annual plans are $2.75 per month, billed as $32.99 per year. A full breakdown is at dolphinradar.com/plan.

Final Thoughts

The concerns around PeekViewer come from documented, publicly reported sources, specifically a TechCrunch investigation in February 2026, not from competitor claims. Whether that changes your decision depends on what you need.

If your goal is anonymous story viewing, likes and follow tracking, and behavioral analytics for public Instagram accounts, DolphinRadar covers all of that without requiring Instagram credentials, without claiming access to private accounts, and with no data breach history on record.
