Subprocessors and data flow
Every outside service involved in delivering Metric Vault, exactly what each one receives, and what never leaves the platform.
Last updated 2026-08-06
Summary#
Metric Vault is built on a small set of outside services. This page names them, states exactly what each one receives, and — more usefully for a vendor review — states what they do not receive. The short version: the search-data and AI providers get the domain, keyword or content you submitted and nothing about who submitted it; Stripe gets your billing relationship and never gives us your card number; and no provider receives your reports or your account credentials.
The formally published sub-processor list is on the GDPR & Data page at metricvaultai.com/legal/gdpr. This page is the operational version of it, mapped to the features that trigger each transfer.
Overview#
Every processor is bound by a data processing agreement requiring it to process personal data only on our instructions, apply appropriate security measures, and assist us with our own obligations. None is authorised to use your data for its own purposes.
Three principles decide what leaves the platform, and they are worth reading before the tables.
Providers receive the query, not the querier. When you run a tool, the domain or keyword goes to the data provider. Your email address does not. There is nothing in a provider request that identifies which account made it.
Nothing is sent to train a model. We do not use your data to train third-party AI models, and we do not permit our providers to.
Card data never transits our systems. Payment details are entered on Stripe's pages and are never processed by, stored on, or passed through Metric Vault.
The published sub-processor list#
These are the processors named on the GDPR & Data page.
| Sub-processor | Location | Role |
|---|---|---|
| Stripe, Inc. | USA | Payment processing and subscription billing |
| DataForSEO | Ukraine / International | Search, keyword, backlink and SERP data |
| Uptime Robot | USA | Platform availability monitoring |
| Cloud hosting and infrastructure providers | USA | Server, database and platform delivery |
Every service that touches data, and what it receives#
This is the fuller operational map, including the services that sit inside the "hosting and infrastructure" line above and the providers behind individual features.
| Service | What triggers it | What it receives | What it does not receive |
|---|---|---|---|
| Cloudflare | Every request. It is the hosting, edge network, application database and object storage | Everything the platform stores, as the infrastructure it runs on. Also the interface strings sent for translation, and image prompts when blog artwork is generated | — |
| Managed authentication provider | Sign-in, sign-up, password reset, Google sign-in | Your email address, display name and password, held as an encrypted hash | Your analyses, reports, billing details or usage |
| Stripe | Upgrading, managing a subscription, every renewal | Your email address, the plan you chose, your billing address and the card details you enter on Stripe's own pages | Your analyses, reports, keywords, domains or usage data |
| DataForSEO | Running any tool that needs search, keyword, backlink or SERP data | The domain, URL, keyword or brand you submitted, plus the settings for that run such as country and device | Your email address, account details, plan, or anything identifying who ran the query |
| Google PageSpeed Insights | PageSpeed and Core Web Vitals checks | The URL you submitted and whether you asked for mobile or desktop | Anything about your account |
| Google Search Console and Analytics | Only if you connect them | The authorisation you granted, the site you selected, and the date range and dimensions of each query. Data flows mainly the other way: Google returns your own measured figures | Your Metric Vault password, other customers' data, or anything from tools you have not connected |
| OpenAI | Most research and analysis tools, the assistant, and in-app chat | The prompt: the domain, keyword or brand you submitted, the provider data retrieved for it, and content you pasted into a writing tool | Your email address or account details |
| Anthropic (Claude) | Long-form writing, strategic synthesis, web-grounded checks, the responsiveness analyzer | The same shape of prompt | The same |
| Google (Gemini) | AI visibility measurement, as one of the assistants tested | The brand or prompt being measured | The same |
| Perplexity | Fact checking with citations, source discovery, and AI visibility measurement | The brand, query or claim being checked | The same |
| Transactional email provider | Team invitations, alert emails, scheduled report notifications | The recipient's address and the content of that message | Your reports, unless you scheduled one to be delivered by email |
| Uptime Robot | Continuous availability checks | Nothing of yours. It checks whether the platform responds. The public status page is stats.uptimerobot.com | Any customer data at all |
| Social platforms — LinkedIn, X, Facebook, Instagram, Threads, TikTok | Only if you connect a channel | The authorisation you granted, and the posts you publish or schedule through the composer | Anything from the rest of the platform |
| Stock image search | Searching for a stock image in the blog studio | The search term you typed | Anything about your account |
| AI image provider | Generating blog artwork | The image prompt | Anything about your account |
| Translation provider | Translating dynamic interface text into another language | The interface strings being translated | Customer data. Report content is translated as text with data values masked |
Several of these are optional and never activate unless you use the feature. Search Console, the social channels, the blog studio and its image tools all require an explicit connection or action from you. See Integrations for what each integration does and Disconnecting an integration for removing one.
What leaves the platform when you run a tool#
Worth tracing once, because it is the question every vendor review asks.
- You submit a domain, URL, keyword or brand in the dashboard.
- The server checks your plan, your credits and, for any URL you supplied, that the target is a public internet address rather than a private or internal one.
- The query is sent to the relevant provider — DataForSEO for search data, Google for page speed, an AI provider for analysis or writing. Your account identity is not part of that request.
- The provider's answer comes back, is analyzed and scored, and the finished result is stored against your account.
- If the tool is one of the cached ones, the provider's answer is also kept in a shared cache keyed by the tool and the query, so the next lookup of the same thing does not re-bill the provider. That cache carries no account identifier. See Result caching and freshness.
Nothing in that path sends your reports, your saved work, your team, your billing details or your credentials anywhere.
What never goes to a third party#
| Never sent | Note |
|---|---|
| Your password | It is held only by the authentication provider, as a hash |
| Your reports and saved results | They stay on the platform. The exception is one you deliberately export, email or share by link |
| Your credit and usage figures | Metering is internal |
| Your team list | Except that an invitation email necessarily reaches the invitee's address |
| Your card number | It is never on our systems to send |
| Your browsing history | The Chrome extension reads the active tab address only when you click it. See The Chrome extension |
Notes for a vendor review#
- Transfers. All of the above are US-based or international. For EEA, UK and Swiss customers those transfers are covered by Standard Contractual Clauses or the UK IDTA. Copies are available on request. See GDPR and compliance.
- Changes. If we onboard a new sub-processor that materially affects your data, the GDPR page and this article are updated, and we notify you where required.
- A complete named list. The published list above names the processors we formally disclose. If your assessment needs every vendor named, including the hosting and identity providers, write to
hello@metricvaultai.comand we will provide the current list rather than leaving you to infer it. - Documents. Ask the same address for a data processing agreement, the applicable SCCs or IDTA, or a completed security questionnaire.
- Provider behavior. Where the data comes from explains what each data source actually measures and how fresh it is, and AI models used across the platform maps each feature to the model behind it. Those two are the right pages when the question is about data quality rather than data protection.
