Session Stacker FAQ

How is Session Stacker different from other task managers?

While traditional task managers excel at organizing large backlogs and complex projects, they often don't solve the "restart problem." Session Stacker is specifically designed for that single moment of transition. It creates a cooperative handoff between sessions, ensuring immediate clarity on what to do right now, without requiring you to re-prioritize a full board or list.

What happens if I don't complete my defined next step in a session?

The system is flexible and understands that plans can change. If your next step shifts, you simply update it at the end of your current session. The core discipline is the act of defining a clear next step, not necessarily completing the previous one. This maintains the cooperative loop and ensures you always have a starting point.

Can I use Session Stacker with a team?

Session Stacker is built intentionally for solo builders and side-hustlers. Its philosophy centers on the individual's discipline loop and protecting personal build windows. For collaborative team project management with assigned tasks and sprints, other tools would be more suitable for fostering group synergy.

Is my data safe and private?

Yes. According to the provided legal links, Session Stacker has a Privacy Policy and Terms of Service that govern data handling. You can review these documents on their website for specific details on data security, usage, and your privacy rights as a user collaborating with the tool.
