Private cloud storage for your photos, videos, files and folders. Back up your important data, free up space on your devices, and keep your files under your control. Built for privacy and data sovereignty. Private & encrypted Your files are encrypted on your device before they leave it and can only be decrypted with your private key. Your private key stays under your control. Neither DeNet nor Datakeepers can access or decrypt your files. Decentralized Your encrypted files are split into multiple parts and distributed across a decentralized network of independent storage providers called Datakeepers. No single Datakeeper stores your complete file, creating a storage system without a single point of failure. Automatic backup Automatically back up photos, videos, files and folders from your devices. Keep important data protected and free up space without deleting the files you want to keep. One account across your devices Use the same private key across mobile, Windows, macOS and Linux. Access and synchronize your files across devices with one account. Flexible storage, not a fixed subscription You pay for the storage you actually use — not for a fixed subscription period. Your storage balance is consumed based on the amount of data you store. If you don't store data, your balance isn't consumed. Store more, and your balance is used faster. Store less, and it lasts longer. Free to install. No ads. DeNet is free to install and contains no third-party advertising. Explore the DeNet ecosystem The DeNet app gives you access to more than storage. You can also run a Watcher Node directly from the same app and participate in the ecosystem built on the DeNet Storage Protocol.

About

SLO/SLA Calc

This tool helps engineers and operators model system availability and evaluate designs before deployment. It calculates availability for various configurations, estimates device reliability, and allows users to build and visualize complex systems. Generate professional PDF reports and review key definitions for availability and reliability.

Highlights
  • Calculate system and device availability
  • Model series, parallel, and N:M designs
  • Estimate device availability using MTBF, MTTR
  • Save and reuse devices/subsystems as Blocks
  • Build larger Systems by connecting Blocks
  • Visualize system architecture
  • Generate and share PDF reports

SLO/SLA Calc helps engineers, architects, SREs, and operators move from Device assumptions to resilient System decisions before deployment. Model operational availability and time-bound Mission Reliability. Calculate Series, Parallel, N:M, and Cross-Connected topologies. Estimate Device Availability from manufacturer MTBF or documented generic estimates, then account for repair time, spare logistics, support agreements, EOL sourcing, and redundant power. Review exactly how each assumption affects the result. Save Devices and subsystems as reusable Blocks, then arrange them into larger Systems. With Live Modeling, apply temporary failures to Blocks, internal Components, and switches. Remaining Availability updates immediately while animated Red and Blue paths show which inputs survive. Shared paths become Purple, and optional output switches select a healthy single handoff. MODEL AVAILABILITY - Calculate System and Device Availability - Review a transparent Device calculation breakdown - Edit the defaults used for new Device calculations - Translate availability into downtime per day, week, month, or year - Model Series, Parallel, heterogeneous N:M, and Cross-Connected designs - Reuse saved Devices as named topology Components EVALUATE A MISSION - Estimate Mission Reliability for a defined duration in hours, days, or weeks - Use stored MTBF or an explicit availability-only assumption - Compare Mission Success, Interruption Risk, and any-Component failure probability - See expected failed Components and the weakest individual contributor - Distinguish provided, estimated, assumption-based, and mixed data BUILD AND TEST SYSTEMS - Assemble Systems from reusable Blocks and ordered Stages - Use Direct or Full Cross multi-path Handoffs - Add optional output switches and explicit Ideal Paths - Simulate Block, Component, and switch failures - Trace surviving flows in portrait or full-screen landscape COMPARE AND SHARE - Compare complete Systems and quantify downtime reduction - Evaluate a design against a target SLO - See remaining or exceeded error budget - Generate and share professional PDF reports - Export, share, preview, and import editable JSON-based .slosla files - Edit imported Block Components and recalculate the design Learn through an expanded Guided Tour, worked examples, formulas, model assumptions, and practical design guidance. SLO/SLA Calc works entirely offline and stores Device defaults, Blocks, and Systems locally on your device. No account is required. Files leave your device only when you choose to export or share them. One purchase unlocks the complete app. No ads, analytics, tracking, subscriptions, or in-app purchases.

Verdict

The call

The clearest difference is price: DeNet at Free against SLO/SLA Calc's $1.99. DeNet also leads on ratings volume (1.6K vs 1). SLO/SLA Calc's advantage is in-app purchases (none vs 5) and review sentiment (100% vs 78%). On update cadence, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

SLO/SLA Calc holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: DeNet has 1.6K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 78% of DeNet's written reviews are positive against 100% of SLO/SLA Calc's.

UpkeepUpdate frequency

DeNet ships an update every 10 days, SLO/SLA Calc every 11 days. The most recent releases landed on October 30, 2026 and October 9, 2026 respectively.
