The record

Purpose: Open Sound Meter is a sound measurement application for tuning audio systems in real time.
Analysis: Its measurements include real-time spectrum analysis, magnitude and phase response, impulse response, coherence, group delay, spectrogram and SPL.
Project files: Measurement projects can be saved and reopened, with each stored measurement including its settings.
Additional tools: Additional features include a wavelength calculator, virtual summation, difference and averaging, a signal generator, equalization and modelling.
Open source: The maker describes the desktop version as open source and invites contributions on GitHub.
Remote API: The Remote API shares active and stored measurements between Open Sound Meter instances and is also available to third-party applications.
Cloud data: Cloud features store measurement and settings data, but the maker says audio recordings and raw audio data are not transmitted to or stored in the Cloud.
Hosting: The maker says its website, accounts and Cloud services are hosted on a dedicated server in Germany operated by Hetzner Online GmbH.
Accounts: The privacy policy says account passwords are stored only as a hash and account data is retained while the account exists.
Cloud retention: After a Cloud subscription ends, data remains viewable for six months, hidden for a further six months, and then is deleted if the subscription is not renewed.
Support: Users can contact support by email or post in the Facebook group, and the maker offers paid consultations in Russian or English.
Consultation price: Paid consultations are listed from $100 for one session lasting 1–1.5 hours.
Device limit: Desktop Pro and Pro + Cloud entitlements are for one user on up to five simultaneously activated devices.
