Privacy Notes
Publicly stated data-handling notes that matter when evaluating Spark.
Spark says it never sells user data, and the privacy policy gives California residents CCPA opt-out rights while saying the app follows GDPR and other privacy laws.
The AI Assistant page says your emails and request history are processed locally on your device, and only the emails most related to your query are sent to the AI provider.
The email storage article says the content of your email stays on your provider's server, while Teams and Send Later data are stored on Spark's servers in encrypted form.
Spark's shared inbox help pages say shared accounts are built for teams, can be created without sharing credentials, and support team collaboration workflows.

Product Snapshot
Spark is an AI email and calendar app from Readdle. It is built for people who want to manage several inboxes, collaborate on mail, and use AI inside a desktop and mobile mail workflow.
What You Can Do With It
- Combine multiple email accounts into a single inbox and use Smart Inbox, Smart Search, and scheduled send to manage volume.
- Filter noisy senders with Gatekeeper and priority controls so new or low-value mail stays out of the way.
- Use Spark +AI to draft, rewrite, translate, summarize, and act on emails, attachments, meetings, and calendar events.
- Keep calendars and team email workflows together with shared inboxes, shared drafts, private comments, assignments, and read statuses.
Why It Stands Out
Spark ties inbox management, calendar handling, team collaboration, and AI assistance into one product instead of leaving those jobs across separate tools.
Tradeoffs To Know
- The more useful collaboration and AI features live on paid plans, so the free tier is mostly an evaluation path.
- Pricing is per user for Plus and Pro, which matters once a team scales past a few seats.
- Some integrations and actions are still presented as rolling out on the pricing page, so the roadmap is part of the buying decision.
- It is broad enough that users who only want a simple personal inbox may not need the full set of features.
