PostHog调整数据保留策略：新付费计划默认2年
Updated events data retention for new paid plans
SaaS产品定价与资源管理的经典案例，清晰展示了如何通过调整默认参数和分层套餐来优化单位经济模型并控制成本，对独立开发者极具参考价值。
Starting November 5, 2026, new paid plans on PostHog Cloud will have a 2-year events data retention period by default, down from 7 years. Existing paid plans keep their 7-year events data retention period unless they downgrade their plan or platform package.
自 2026 年 11 月 5 日起，PostHog Cloud 的新付费计划将默认保留 2 年的事件数据，较之前的 7 年有所缩短。现有付费计划将继续保留 7 年的事件数据保留期，除非其降级计划或平台套餐。
The table below shows how retention is changing by plan:
下表显示了各计划的保留期变更情况：
| Plan | Retention before November 5, 2026 | Retention on or after November 5, 2026 |
|---|---|---|
| Free | 1 year | 1 year |
| Pay-as-you-go | 7 years | Up to 2 years (Default = 2 years) |
| Pay-as-you-go with Boost | 7 years | Up to 3 years (Default = 2 years) |
| Pay-as-you-go with Scale | 7 years | Up to 5 years (Default = 2 years) |
| Pay-as-you-go with Enterprise | 7 years | Up to 7 years (Default = 2 years) |
| 计划 | 2026 年 11 月 5 日之前的保留期 | 2026 年 11 月 5 日及之后的保留期 |
|---|---|---|
| 免费 | 1 年 | 1 年 |
| 按量付费 | 7 年 | 最长 2 年（默认 = 2 年） |
| 按量付费 + Boost | 7 年 | 最长 3 年（默认 = 2 年） |
| 按量付费 + Scale | 7 年 | 最长 5 年（默认 = 2 年） |
| 按量付费 + Enterprise | 7 年 | 最长 7 年（默认 = 2 年） |
Why are we making this change?
我们为何做出此项变更？
Over the past year, many customers have asked us to shorten their events data retention period, and others were surprised to learn we keep events for 7 years. That feedback led us to review our retention policy and compare it with others in our industry. Here's what we found:
在过去一年中，许多客户要求缩短其事件数据的保留期，而其他客户则对我们保留 7 年事件数据感到惊讶。这些反馈促使我们审查了自身的保留政策，并与行业内的其他做法进行了比较。以下是我们的发现：
- 2 years is the industry standard. Most non-enterprise plans keep events data for 2 years.
- Old data rarely gets queried. The vast majority of queries run on data less than a year old.
- Storing 7 years of data is expensive. We've been paying to store data that most of you weren't using and didn't need us to keep.
- 2 年是行业标准。大多数非企业级计划仅保留 2 年的事件数据。
- 旧数据很少被查询。绝大多数查询针对的是不到一年的数据。
- 存储 7 年的数据成本高昂。我们一直在为存储大部分用户未使用且无需保留的数据付费。
For these reasons, we've decided to change our retention periods and give you more control over how long we store your data.
基于上述原因，我们决定更改保留期，并让您拥有更多控制权，以决定我们存储您数据的时间长度。
How does this impact existing customers?
这对现有客户有何影响？
Existing paid organizations: You keep 7-year events retention while you stay on your current plan and platform package, or move to an upgraded platform package. If you downgrade to the Free plan, or downgrade your platform package, you'll move to the new default retention period for your plan.
现有付费组织：只要您保持在当前计划和平台套餐上，或升级到更高的平台套餐，您将保留 7 年的事件数据保留期。如果您降级到免费计划，或降级您的平台套餐，则将适用该计划的新默认保留期。
Existing free organizations: You'll keep 1-year retention. If you upgrade to pay-as-you-go on or after November 5, you'll get the 2-year default. With a platform package, you get access to longer retention periods.
现有免费组织：您将保留 1 年的保留期。如果在 2026 年 11 月 5 日或之后升级到按量付费，您将获得 2 年的默认保留期。通过平台套餐，您可以访问更长的保留期。
What happens to my data after the events data retention period ends?
事件数据保留期结束后，我的数据会发生什么？
When an event's timestamp goes past your retention period, it is considered expired. Expired events may be deleted at any point, and we can't restore deleted events.
当事件的时间戳超过您的保留期时，即被视为已过期。过期的事件可能在任何时间点被删除，且我们无法恢复已删除的事件。
We do not automatically delete events as soon as they expire, so they may be stored longer than your retention period, for two reasons:
我们不会在事件过期后立即自动删除它们，因此它们可能会被存储超过您的保留期，原因如下：
- Not all customers are aware that their retention period has ended, and we want to give them time to extend it
- We delete events in batches, so there is a delay between when an event expires and when it is deleted
- 并非所有客户都意识到他们的保留期已结束，我们希望给予他们延长保留期的时间
- 我们批量删除事件，因此事件过期与删除之间存在延迟

How can I extend my events data retention period in PostHog?
如何在 PostHog 中延长我的事件数据保留期？
Add a platform package, then increase your events data retention period in your organization or project settings. A data retention period can be set up to 3 years on Boost, 5 years on Scale, and 7 years on Enterprise. Adding a package doesn't automatically extend your data retention period.
添加平台套餐，然后在组织或项目设置中增加你的事件数据保留期。在 Boost 上最多可设置 3 年，Scale 上为 5 年，Enterprise 上为 7 年。添加套餐不会自动延长你的数据保留期。
For more information on changing your events data retention period, see the events data retention docs.

Can I export data out of PostHog?
我可以从 PostHog 导出数据吗？
Yes, if you'd prefer not to upgrade your package, or you need to keep data for longer than 7 years, you can send it to your own data warehouse with a batch export.
是的，如果你更倾向于不升级套餐，或者需要保留超过 7 年的数据，你可以通过批量导出将其发送到你自己的数据仓库。
